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 Ω loads (series 75 Ω resistor and 75 Ω 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 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 2.6 V and amplified 6 dB to produce
1.1 VP-P (typical) into a series 75 Ω resistor and 75 Ω cable
load. During standby (Pin 3 grounded), the TK15407
consumes only 119 µW 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.
