TOSHIBA Bipolar Linear Integrated Circuit Silicon Monolithic
TA2154AFN
TA2154AFN
1.5 V 1 Chip Tuner IC (for Digital Tuning System)
TA2154AFN is developed for 1.5 V headphone stereos. It
incorporates all the functions of an FM/TV front end, AM/FM IF,
and FM multiplex.
The IC can be used for IF count digital tuning systems. Since
the IC divides the buffer output frequency by 16 while
suppressing the FM/TV local oscillation level, the IC can suppress
unnecessary emission, facilitating conformance to the new FCC
specifications (part 15).
Features
· FM/TV local oscillator level is low (Built-in auto level control
circuit)
Weight: 0.17 g (typ.)
· Suitable for combination with digital tuning system, which is
included IF counter.
· One terminal type AM/FM IF count output for IF counter of digital tuning system.
· AM: 450 kHz
· FM: 10.7 MHz
· One terminal type FM/TV local oscillator.
· Local oscillator buffer output terminal shared by AM, FM and TV
· AM: 1/1
· FM: 1/32
· TV: 1/8
· For adopting ceramic discriminator, it is not necessary to adjust the FM quad detector circuit.
· Built-in FM MPX VCO circuit.
· Low supply current (VCC = 1.2 V, Ta = 25°C)
Iccq (AM) = 5.0 mA (typ.)
Iccq (FM) = 13.0 mA (typ.)
Iccq (TV) = 13.5 mA (typ.)
· Operating supply voltage: VCC = 1.0~2.2 V (Ta = 25°C)
· Monaural operating supply voltage: VCC = 0.95~2.2 V (Ta = 25°C)
