UHF / VHF TUNER IC
The TA1281F, TA1281FA, and TA1281FN are TV tuner ICs 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.
FEATURES
= Supply voltage
: 5V
= VHF, CATV bands : MIX · OSC
= UHF band
: MIX · OSC
= Built-in IF amp
= IF unbalanced output
= Low power dissipation
Note:
These devices are easy damaged by high static voltage
or electric fields. In regards to this, please handle with
care.
