3 V AM/FM 1 Chip Tuner IC (for Digital Tuning System)

TA2149BN, TA2149BFN are AM/FM 1 chip tuner ICs, which

are designed for portable Radios and 3 V Head phone Radios.

This is suitable for Digital Tuning System Applications. FM

Local Oscillation Voltage is set up low relativity, for NEW FCC.

Functions

· For NEW FCC.

· Suitable for combination with Digital Tuning System which is

included IF Counter.

· Adjustable for IF count output sensitivity by external

resistance of pin 17 (FM only).

· One terminal type AM/FM IF count output for IF counter of

Digital Tuning System.
