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.

Features

● Low power supply voltage: VDD=1.8 to 2.5V

● Low power consumption: 5mW (VDD=2.0V, FIN=100MHz)

● High-speed operation: FIN=175MHz

● Frequency dividing ratios in reference frequency dividing stage: 5 to 131,071

● Frequency dividing ratios in comparator stage: 272 to 262,143

● Lock detector output pin

● Two types of phase comparator output

- Internal charge pump output

- Output for external charge pump

● Output monitor pins for both comparator and reference frequency dividing stages
