LC72133M, 72133V are phase-locked loop frequency synthesizer LSI circuits for use in radio tuners. It supports low-voltage (2.7 to 3.6 V) operation and can implement high-performance AM/FM tuners easily.
The LC72133M and LC72133V are low-voltage (2.7 to 3.6 V) phase-locked loop frequency synthesizer LSI circuits designed for use in AM/FM radio tuners. They support high-performance tuning with built-in MOS transistors for active low-pass filters and dedicated I/O ports using the CCB serial bus format.
