Overview
The MN6152U is a CMOS LSI for a phase-locked loop (PLL) frequency synthesizer with serial data input.
It consists of a two-coefficient prescaler, variable frequency divider, phase comparator, and charge pump.
It offers high-speed operation on a low power supply voltage (1.8 to 2.5 V) and low power consumption (5 mW for VDD=2.0 V, FIN=100 MHz).
Other features include intermittent operation by the power save (PS) control signal and high-speed pull-in that rapidly corrects the phase differences occurring at the start of operation.
