Single Supply Video Driver with Reconstruction Filter and Charge Pump
The ISL59831 is a single supply video driver with reconstruction filter and charge pump. It is designed to drive SDTV displays with luma (Y) or composite video (CV) signals. It operates on a single supply (3.0V to 3.6V) and generates its own negative supply (-1.9V) using a regulated charge pump. Input signal can be AC or DC coupled. When AC coupled, the sync tip clamp sets the blank level to ground at the output, ensuring that the sync-tip voltage level is set to approximately -300mV at the back-termination resistor of a standard video load. The ISL59831 is capable of driving two AC or DC coupled standard video loads. The device also features a 4th order Butterworth reconstruction filter with nominal -3dB frequency set to 9.1MHz, providing 44dB of attenuation at 27MHz. When powered down, the device draws 2A supply current. Nominal operational current is 15mA. The ISL59831 is available in 12 Ld TDFN package and operates from the -40C to +85C temperature range.

ISL59831 Description of Operation and Application Information
Theory of Operation
The ISL59831 is a single supply video driver with a reconstruction filter and an on-board charge pump. It is designed to drive SDTV displays with luma (Y) or composite video (CV) signals. The input signal can be AC-coupled or DC-coupled. When AC-coupled, the sync tip clamp sets the blank level to ground at the output. The ISL59831 is capable of driving two AC-coupled or DC-coupled standard video loads and has a 4th order Butterworth reconstruction filter with nominal -3dB frequency set to 9.1MHz, providing 44dB of attenuation at 27MHz. The ISL59831 is designed to operate with a single supply voltage range ranging from 3.0V to 3.6V. This eliminates the need for a split supply with the incorporation of a charge pump capable of generating a bottom rail as much as 1.9V below ground; providing a 5.2V range on a single 3.3V supply. This performance is ideal for NTSC video with negative-going sync pulses.
Video Performance
DIFFERENTIAL GAIN/PHASE For good video performance, an amplifier is required to maintain the same output impedance and the same frequency and phase response as DC levels are changed at the output. This is especially difficult when driving a standard video load of 150 because of the change in output current with changing DC levels. Special circuitry has been incorporated into the ISL59831 for the reduction of output impedance variation with the current output. This results in outstanding differential gain and differential phase specifications of 0.04% and 0.35, while driving 150 at a gain of +2V/V. Driving higher impedance loads would result in similar or better differential gain and differential phase performance. NTSC The ISL59831, generating a negative rail internally, is ideally suited for NTSC video with its accompanying negative-going sync signals.
Output Amplifier
The ISL59831 output amplifier provides a gain of +6dB. The output amplifier is able to drive a 2.8VP-P video signal into a 150 load to ground. The output is a highly-stable, low distortion, low power, high frequency amplifier capable of driving moderate capacitive loads.
Driving Capacitive Loads and Cables
The ISL59831, internally-compensated to drive 75 cables, will drive 220pF loads in parallel with 150 with less than 1.5dB of peaking.
AC-Coupled Inputs
SYNC TIP CLAMP The ISL59831 features a sync tip clamp that sets the black level of the output video signal to ground. This ensures that the sync-tip voltage level is set to approximately -300mV at the back-termination resistor of a standard video load. The clamp is activated whenever the input voltage falls below 0V. The correction voltage required to do this is stored across the input AC-coupling capacitor. Refer to "Block Diagram/Typical Application Circuit" on page 2 for a detailed diagram.
Input/Output Range
The ISL59831 has a recommended dynamic input range of 0VP-P to 1.4VP-P. This allows the device to handle the maximum possible video signal input. As the input signal moves outside the specified range, the output signal will exhibit increasingly higher levels of harmonic distortion. As the load resistance becomes lower, the current drive capability of the device will be challenged and its ability to drive close to each rail is reduced.
The Charge Pump
The ISL59831 charge pump provides a bottom rail up to 1.9V below ground while operating on a 3.0V to 3.6V power supply. The charge pump is internally regulated and is driven by an internal 15MHz clock. To reduce the noise on the power supply generated by the charge pump, connect a low pass RC-network between CPVEEOUT and VEEIN. See "Block Diagram/Typical Application Circuit" on page 2 for further information.
DC-Coupled Inputs
When DC-coupling the inputs ensure that the lowest signal level is greater than +50mV to prevent the clamp from turning on and distorting the output. When DC-coupled the ISL59831 shifts the signal by -550mV from input to output.
Amplifier Disable
The ISL59831 can be disabled and its output placed in a high impedance state. The turn-off time is around 10ns and the turn-on time is around 30s. The turn-on time is greater in length because extra time is given for the charge pump to settle before the amplifier is enabled. When disabled, the amplifier's supply current is reduced to 2A typically, reducing power consumption. The amplifier's power-down can be controlled by standard TTL or CMOS signal levels at the ENABLE pin. The applied logic signal is relative to the GND pin. Applying a signal that is less than 0.8V above
The CPVEEOUT Pin
CPVEEOUT is the output pin for the charge pump. Keep in mind that the output of this pin is generated by the internal charge pump and a fully regulated supply that must be properly bypassed. Bypass this pin with a 0.1F ceramic capacitor placed as close to the pin and connected to the ground plane of the board. 9
FN6266.0 March 29, 2007
ISL59831
GND will disable the amplifier. The amplifier will be enabled when the signal at ENABLE pin is 2V above GND. By setting the two PDMAX equations equal to each other, we can solve the output current and RLOAD to avoid the device overheat.
Output Drive Capability
The maximum output current for the ISL59831 is set at 50mA. Maximum reliability is maintained if the output current never exceeds 50mA, after which the electromigration limit of the process will be exceeded and the part will be damaged. This limit is set by the design of the internal metal interconnections.
Power Supply Bypassing and Printed Circuit Board Layout
Strip line design techniques are recommended for the input and output signal traces. As with any high frequency device, a good printed circuit board layout is necessary for optimum performance. Lead lengths should be as short as possible. The power supply pin must be well bypassed to reduce the risk of oscillation. For normal single supply operation, a single 4.7F tantalum capacitor in parallel with a 0.1F ceramic capacitor from VCC and VCP to GND will suffice. For good AC performance, parasitic capacitance should be kept to a minimum. Use of wire-wound resistors should be avoided because of their additional series inductance. Use of sockets should also be avoided if possible. Sockets add parasitic inductance and capacitance can result in compromised performance. Minimizing parasitic capacitance at the amplifier's inverting input pin is also very important.
Power Dissipation
With the high output drive capability of the ISL59831, it is possible to exceed the +150C absolute maximum junction temperature under certain load current conditions. Therefore, it is important to calculate the maximum junction temperature for an application to determine if load conditions or package types need to be modified to assure operation of the amplifier in a safe operating area. The maximum power dissipation allowed in a package is determined according to Equation 1:
T JMAX - T AMAX PD MAX = ------------------------------------------- JA
(EQ. 1)
Where: TJMAX = Maximum junction temperature TAMAX = Maximum ambient temperature JA = Thermal resistance of the package The maximum power dissipation actually produced by an IC is the total quiescent supply current times the total power supply voltage, plus the power in the IC due to the load, or: for sourcing:
V OUT i PD MAX = V S x I SMAX + ( V S - V OUT i ) x ----------------RL i
(EQ. 2)
for sinking:
PD MAX = V S x I SMAX + ( V OUT i - V S ) x I LOAD i (EQ. 3)
Where: VS = Supply voltage ISMAX = Maximum quiescent supply current VOUT = Maximum output voltage of the application RLOAD = Load resistance tied to ground ILOAD = Load current i = Number of output channels
