| TK15400 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 Internal Summing Circuit of Y/C Signal s 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 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 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 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 2.0 V and amplified 6 dB to produce 1.3 VP-P (typical) into a series 75 resistor and 75 cable load. During standby (Pin 5 grounded), the TK15400 consumes only 113 W of power. Nominal power dissipation (no input) is typically 168 mW. The TK15400M is available in the SSOP-12 Surface Mount Package.
