TK15409 75 Ω VIDEO LINE DRIVER FEATURES APPLICATIONS ■ Internal Y-C Summing Circuit ■ Voltage Gain is 6 dB Fixed ■ Internal 75 Ω Driver ■ Active High ON/OFF Control ■ Very Low Standby Current (typ. ISTBY ≤ 25 µA) ■ Very Small Output Capacitor Using SAG Function Pin ■ Very Small Package (SOT23L-8) ■ Single +5 V Power Supply Operation ■ ■ ■ ■ ■ ■ Video Equipment Digital Cameras CCD Cameras TV Monitors Video Tape Recorders LCD Projectors DESCRIPTION TK15409 Operating from a single +5 V supply, the TK15409 is a video line driver IC that takes standard Y and C analog inputs and provides a composite analog output for driving 150 Ω loads (75 Ω resistor and 75 Ω cable load). 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; the chromanance (C) input is biased at 2.0 V and amplified 6 dB. The internal 1.5 kΩ SAG function resistor provides gain compensation for low frequency signals. During standby (Pin 5 grounded), the TK15409 consumes only 127 µW of power. Nominal power dissipation (no input) is typically 90 mW. C-INPUT Y-INPUT N/C VCC SAG GND 01S STANDBY OUTPUT BLOCK DIAGRAM The TK15409M is available in the very small SOT23L-8 surface mount package.
