Description
The SC72131S is a phase-locked loop (PLL) LSI designed for digital tuning systems (DTS). It is used to configure high-performance digital tuning systems like radio/cassette players, making it easy to implement high-performance AM/FM tuners.
Specifications and features
- Built-in prescalers, operating at input frequencies ranging from 10 to 160MHz during FMIN input and 0.5 to 40MHz during AMIN input.
- 12 possible reference frequencies with 4.5 or 7.2 MHz crystal: 1, 3, 5, 9, 10, 3.125, 6.25, 12.5, 15, 25, 50, and 100 kHz.
- Built-in 20-bit general-purpose counter for measuring intermediate frequency (IF), with IF input frequencies ranging from 0.4MHz to 12MHz.
- Includes an unlock detector circuit, a dead zone control circuit, and a deadlock clear circuit.
- Built-in MOS transistor for forming an active low-pass filter.
- 4 N-channel open-drain output ports (OFF withstanding Voltage: 13V) and 2 input or output ports.
- All functions controlled through 4 serial bus lines using serial data I/O.
- Operating ranges: supply voltage of 5.0±0.5 V and an operating temperature of -40 to +85°C.
- Packages: SDIP-22-300-1.78 and SOP-20-300-1.27.
