TK15400 75 Ω VIDEO LINE DRIVER FEATURES APPLICATIONS ■ Fixed Gain (6 dB) ■ Internal 75 Ω Drivers ■ Very Small Output Capacitor Using SAG Function Pin ■ Active High ON/OFF Control ■ Very Low Standby Current (typ. ISTBY ≤ 25 µA) ■ Internal Summing Circuit of Y/C Signal ■ Single +5 V Power Supply Operation ■ ■ ■ ■ ■ ■ Video Equipment Digital Cameras CCD Cameras TV Monitors Video Tape Recorders LCD Projectors DESCRIPTION TK15400 Operating from a single +5 V supply, the TK15400 is a triple video line driver IC that takes standard Y/C analog inputs and provides simultaneous Y/C and composite analog outputs for driving 75 Ω lines. Internal summing of the Y and C inputs is performed to produce the composite video output. The luminance (Y) input is clamped at 1.25 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 2.0 V and amplified 6 dB to produce 1.3 VP-P (typical) into a series 75 Ω resistor and 75 Ω cable load. During standby (Pin 5 grounded), the TK15400 consumes only 113 µW of power. Nominal power dissipation (no input) is typically 168 mW.
