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