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 Ω load. Nominal power dissipation (no input) is typically 56 mW. -INA OUTA +INA VCC +INB GND -INB OUTB 01S The TK15403M is available in the very small SOT23L-8 surface mount package.

V CC + TP1 4.7 µF + 20 kΩ 10 kΩ 5V 33 µF 47 µF 10 kΩ TP2 + SW1 SW1 is closed only when DG and DP are measured. 75 Ω 2 kΩ 47 µF + 2 kΩ TP3 75 Ω 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.

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.
