MN6155

Features:

The MN6155 is a CMOS LSI for a phase-locked loop (PLL) frequency synthesizer with serial data parameter 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 (1.0 to 1.4 V) and low power consumption (1.65 mW for VDD=1.1 V, FIN= RIN=90 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. It also offers two choices for the reference signal: selfexcited operation using the built-in inverter amplifier or use of an external, separately excited oscillator.
