TOSHIBA BIPOLAR LINEAR INTEGRATED CIRCUIT
SILICON MONOLITHIC
TA1284FN
UHF / VHF TUNER IC (Low Phase Noise Oscillator)
TA1284FN
The TA1284FN is TV tuner IC which integrate mixer / oscillator
for VHF and CATV bands, mixer / oscillator for UHF band, and
IF amplifier on a single chip.
Supply voltage of 5 V helps lower power dissipation from the set.
Compact 16-pin SSOP makes the tuner more compact.
FEATURES
l Supply voltage : 5V
l Built-in mixer / oscillator for VHF and CATV bands
l Built-in mixer / oscillator for UHF band
l Oscillator circuits is low phase noise.
l Built-in IF amplifier
l Low power dissipation.
Weight: 0.07g (Typ.)
Note: These devices are easily damaged by high static voltage or electric fields. In this regard, please handle with
care.
