LC72131 Description

Short technical summary and product information.

The LC72131 from Sanyo Denki is a CMOS LSI PLL frequency synthesizer specifically designed for high-performance AM/FM tuners in radio and cassette players. It allows for easy implementation of advanced tuning capabilities.

 

This frequency synthesizer operates with a supply voltage ranging from 4.5V to 5.5V and functions across an operating temperature range of -40°C to +85°C. It supports high-speed programmable dividers for FMIN frequencies from 10 to 160 MHz and AMIN frequencies from 2 to 40 MHz (pulse swallower) or 0.5 to 10 MHz (direct division). The IF counter supports frequencies from 0.4 to 12 MHz for both AM and FM signals.

 

Key features include twelve selectable reference frequencies, a phase comparator with dead zone control, unlock detection, and a deadlock clear circuit. It also incorporates a built-in MOS transistor for an active low-pass filter and supports CCB format serial data I/O for system controller communication. The device is available in DIP22S and MFP20 packages.
