| TK15403 75 VIDEO LINE DRIVER FEATURES s s s s s Internal 75 Drivers 20 MHz Gain Band Width 2 Channel High Speed Operational Amplifiers Very Small SOT23L-8 Package Single +5 V Power Supply Operation APPLICATIONS s s s s s s Video Equipment Digital Cameras CCD Cameras TV Monitors Video Tape Recorders LCD Projectors DESCRIPTION Operating from a single +5 V supply, the TK15403M is a dual video line 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. Nominal power dissipation (no input) is typically 56 mW. The TK15403M is available in the very small SOT23L-8 surface mount package.

V CC + TP1 4.7 F + 10 k 33 F 5V CC 20 k 10 k 47 F TP2 + SW1 SW1 is closed only when DG and DP are measured. 75 2 k 47 F + 75 TP3 2 k MEASUREMENT METHOD 1. Supply Current (ICC) The Pin 7 current is measured with no input signal. 2. 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 voltage at TP2. 3. Frequency Response (fr1 and fr2) The frequency response equation is as follows: fr = 20 log10 V2/V1 Where V1 is the measured TP3 voltage when the TP1 input frequency is set to 1 MHz. For fr1 V2 is the measured TP3 voltage when the TP1 input frequency is set to 5 MHz. For fr2 V2 is the measured TP3 voltage when the TP1 input frequency is set to 10 MHz. These measurements and calculations are taken for both channels. 4. Total Harmonic Distortion (THD) The TP3 signal is measured when a 1 kHz 1 VP-P input signal is applied to TP1. 5. Maximum Output Voltage (VOUT(MAX)) A 1 kHz input signal is applied to TP1 and slowly increased. The output voltage at TP2 is measured at the point the THD reaches 10%. 6. Cross Talk (CT) The Cross Talk equation is as follows: CT = 20 log10 V1/V2 V1 is measured at output B when a 1 MHz input frequency and 1 VP-P input signal voltage is applied to Input A, V2 is measured at Output B when a 1 MHz input frequency and 1 VP-P input signal voltage is applied to Input B. CT is also calculated at the opposite side when V1 is measured at Output A when input signal is applied to Input B and V2 is measured at Output A when input signal is applied to Input A. December 1999 TOKO, Inc. Page 3 TK15403 MEASUREMENT METHOD (CONT.) 7. Signal to Noise Ratio (S/N) The signal to noise ratio is measured at TP3 when the pedestal signal input is applied to TP1. 8. 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. 9. 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.
