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 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.
The TK15400M is available in the SSOP-12 Surface
Mount Package.
