TB2132FNG
3-V AM/FM/TV Single Chip Tuner IC with On-Chip PLL
The TB2132FNG is an IC suitable for 3-V headphone radio and
radio cassette application. It has FM/TV front end, FM IF, FM
stereo decoder, AM function and PLL function on a single chip.
The FM/TV front end is designed to lower the oscillation voltage
of the FM/TV local oscillator, enabling this IC to meet the new
FCC standards.
Features
• Low supply current (VCC = 3 V, Ta = 25°C)
FM: ICC = 18 mA (typ.)
Weight: 0.17 g (typ.)
AM: ICC = 7.5 mA (typ.)
• Operating supply voltage range
: VCC = 1.8 to 5.5 V (Ta = 25°C)
• Tuner block
• Can be used for TV band.
• Enable to meet the new FCC standards.
• Adjustment-free FM quad detector due to ceramic discriminator
• On-chip FM MPX VCO circuit
• PLL block
• Reference frequency: 1 kHz , 1.5625 kHz, 3 kHz, 3.125 kHz, 5 kHz, 6.25 kHz, 12.5 kHz, 25 kHz
• Data transfer is performed with synchronous three-line bus, using pins CE (Chip Enable), CK (Clock) and
DATA (DATA).
• Crystal oscillation frequency: 75 kHz
• IF count method: On-chip 20-bit counter
Note: The TB2132FNG is mounted with lead-free soldering alloys.
Pin 26 (FM/TV OSC) is sensitive to electrostatic discharge. Take care when handling.
