TOSHIBA Bi-CMOS Integrated Circuit Silicon Monolithic
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.
