TK15402 75 VIDEO LINE DRIVER FEATURES s s s s s Gain Set by External Components (6 dB typ.) Internal 75 Drivers Active High ON/OFF Control Very Low Standby Current (typ. ISTBY 25 A) Single +5 V Power Supply Operation APPLICATIONS s s s s s s s RGB Video Line Driver Applications Video Equipment Digital Cameras CCD Cameras TV Monitors Video Tape Recorders LCD Projectors DESCRIPTION Operating from a single +5 V supply, the TK15402 is a triple video driver IC that takes standard video signals as analog inputs and provides buffered analog outputs for driving 150 loads (series 75 resistor and 75 cable load). The standard video input signals (1 VP-P) are typically amplified 6 dB using external components to produce a 2 VP-P signal into an AC-coupled 150 load. During standby (Pin 2 grounded), the TK15402 consumes only 113 W of power. Nominal power dissipation (no input) is typically 98 mW. The TK15402M is available in the SSOP-12 Surface Mount Package.

Supply Current (ICC) The Pin 1 current is measured with no input signal and the Standby Pin (Pin 2) open. 2. Standby Supply Current (ISTBY) The Pin 1 current is measured when the Standby Pin (Pin 2) is connected to ground. 3. Standby Terminal Current (IOS) The Pin 2 current is measured when Pin 2 is connected to ground. 4. Threshold Voltage (High to Low) (VTHL) The Pin 2 voltage is measured at the point which changes the device from operating mode into standby mode. 5. Threshold Voltage (Low to High) (VTLH) The Pin 2 voltage is measured at the point which changes the device from standby mode into operating mode. 6. Voltage Gain (GVA) The voltage gain equation is as follows: GVA = 20 log10 V2/V1 Where V1 is the input voltage at TP1 and V2 is the measured output voltage at TP2. V1 and V2 are measured for the other channels in the same manner. 7. Frequency Response (fr) The frequency response equation is as follows: fr = 20 log10 V2/V1 Where V1 is the measured TP2 voltage when the TP1 input frequency is set to 1 MHz and V2 is the measured TP2 voltage when the TP1 input frequency is set to 5 MHz. Furthermore, V1 is the measured TP2 voltage when the TP1 input frequency is set to 1 MHz and V2 is the measured TP2 voltage when the TP1 input frequency is set to 10 MHz. V1 and V2 are measured for the other channels in the same manner. January 2000 TOKO, Inc. Page 3 TK15402 MEASUREMENT METHOD 8. Total Harmonic Distortion (THD) The TP2 signal is measured when a 1 kHz 1 VP-P input signal is applied to TP1. THD is measured for the other channels in the same manner. 9. Maximum Output Voltage (VOUT(MAX)) A 1 kHz input signal is applied to TP1 and the amplitude is slowly increased. The output voltage at TP2 is measured at the point the THD reaches 10%. VOUT(MAX) is measured for the other channels in the same manner. 10. Cross Talk (CT) The cross talk equation is as follows: CT = 20 log10 V1/V2 Where V1 is measured at output 3 when a 1 MHz 1 VP-P input signal is applied to input 1 or input 2. V2 is measured at output 3 when a 1 MHz 1 VP-P input signal is applied to input 3. Furthermore, V1 is measured at output 2 when a 1 MHz 1 VP-P input signal is applied to input 1 or input 3. V2 is measured at output 2 when a 1 MHz 1 VP-P input signal is applied to input 2. V1 is measured at output 1 when a 1 MHz 1 VP-P input signal is applied to input 2 or input 3. V2 is measured at output 1 when a MHz 1 VP-P input signal is applied to input 1. 11. Signal to Noise Ratio (S/N) The signal to noise ratio is measured at TP3 when a pedestal input signal is applied to TP1. 12. Differential Gain (DG) SW1 is closed to change the input bias voltage. The differential gain is measured at TP3 when a staircase waveform of 10 steps is applied to TP1. 13. Differential Phase (DP) SW1 is closed to change the input bias voltage. The differential phase is measured at TP3 when a staircase waveform of 10 steps is applied to TP1. TYPICAL PERFORMANCE CHARACTERISTICS SUPPLY CURRENT VS.
