Both amplifiers have a fixed gain of 6 dB and can be used in series for 12 dB gain. The luminance (Y) input is clamped at 1.29 V and amplified 6 dB to produce 2 VP-P (typical) into a series 75 Ω resistor and 75 Ω cable load. The internal 1.5 k SAG function resistor provides gain compensation for low frequency signals. The chromanance (C) input is biased at 2.6 V and amplified 6 dB to produce 1.1 VP-P (typical) into a series 75 Ω resistor and 75 Ω cable load. During standby (Pin 3 grounded), the TK15407 consumes only 119 µW of power. Nominal power dissipation (no input) is typically 76 mW. The TK15407 is ideally suited for S-VHS systems.

Standby Terminal Current (IOS) The Pin 3 current is measured when Pin 3 is connected to ground. 4. Threshold Voltage (High to Low) (VTHL) The Pin 3 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 3 voltage is measured at the point which changes the device from standby mode into operating mode. 6. Clamp Voltage (VCMP) The DC voltage at Pin 2 is measured with no input signal. 7. Bias Voltage (VBIAS) The DC voltage at Pin 4 is measured with no input signal. 8. Voltage Gain (GVA) The voltage gain equation is as follows: GVA = 20 log10 V2/V1 Where V1 is the input voltage at TP1 (TP4) and V2 is the measured voltage at TP2 (TP5). 9. Differential Gain (DG) The differential gain is measured at TP3 when a staircase waveform of 10 steps is applied to TP1. January 2000 TOKO, Inc. Page 3 TK15407 MEASUREMENT METHOD (CONT.) 10. Differential Phase (DP) The differential phase is measured at TP3 when a staircase waveform of 10 steps is applied to TP1. 11. Frequency Response (fr) The frequency response equation is as follows: fr = 20 log10 V2/V1 Where V1 is the measured TP3 (TP6) voltage when the TP1 (TP4) input frequency is set to 1 MHz and V2 is the measured TP3 (TP6) voltage when the TP1 (TP4) input frequency is set to 5 MHz. 12. Total Harmonic Distortion (THD) The TP6 signal is measured when a 1 kHz 1 VP-P input signal is applied to TP4. 13. Maximum Output Voltage (VOUT(MAX)) A 1 kHz input signal is applied to TP4 and the amplitude is slowly increased. The output voltage at TP5 is measured at the point the THD reaches 10%.
