TA1281 F, TA1281FA, TAll 281] FN
UHF/VHF TUNER IC
The TA1281F, TA1281FA, and TA1281FN are TV tuner ICs TA1281F
which integrate on a single chip IF amp, a mixer/
oscillator for VHF band and cable TV, together with a
mixer/oscillator for UHF band.
Supply voltage of 5V helps lower power dissipation from
the set. Compact 16-pin SSOP makes the tuner more
compact.

Either apply balanced input to
pins 9 and 10 or ground pin 10
to AC and input to pin 9.

Regulator output.
UHF oscillator
UHF oscillator.
Pin 12 uses both as band
switch. Connecting pin 12 to
VCC via 22kn sets to UHF ;
connecting pin 12 to GND sets
to VHF. To use VHF SW voltage
open rather than GND,
connect a resistor of around
Changing capacitor of 6pF
connected to pins 12 and 15 of
test circuit 2 varies the
oscillation frequency range. Be
careful not to set the constant
too large, because abnormal
oscillation may occur.
