LC72137 Product details

Description

Symbol Pin No. Crystal oscillator connections (75 kHz) FMIN 13 (12) Local oscillator signal input FMIN is selected when the serial data input DVS bit is set to 1. The input frequency range is from 10 to 160 MHz. The input signal passes through the internal divide-bytwo prescaler and is input to the swallow counter. The divisor can be
