| TK15407 75 VIDEO LINE DRIVER FEATURES s Fixed Gain (6 dB) s Internal 75 Drivers s Very Small Output Capacitor Using SAG Function Pin s Active High ON/OFF Control s Very Low Standby Current (typ. ISTBY 25 A) s Very Small SOT23L-8 Package 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 TK15407 is a dual 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). 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 resistor and 75 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 resistor and 75 cable load. During standby (Pin 3 grounded), the TK15407 consumes only 119 W of power. Nominal power dissipation (no input) is typically 76 mW. The TK15407 is ideally suited for S-VHS systems. The TK15407M is available in the very small SOT23L-8 surface mount package.

Supply Current (ICC) The Pin 7 current is measured with no input signal and the Standby Pin (Pin 3) open. 2. Standby Supply Current (ISTBY) The Pin 7 current is measured when the Standby Pin (Pin 3 ) is connected to ground. 3. 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%.
