252MI-52LF

Overview

The Renesas 252MI-52LF is a low-cost, dual-output field programmable clock synthesizer. It generates two output frequencies ranging from 314 kHz to 200 MHz using up to three reference inputs. The device operates on a single 3 V to 5.5 V supply and features an 8-SOIC package. Key electrical parameters include a maximum output frequency of 200 MHz, a maximum jitter of 50 ps, and a duty cycle of up to 55%. It supports spread spectrum clocking for EMI reduction.

Feature Summary

• Dual-output clock generation capability with independent frequency control
• Field programmable architecture allowing flexible configuration via serial interface
• Spread spectrum clocking functionality designed to minimize electromagnetic interference

Applications

• High-speed data communication systems requiring precise clock synthesis
• Computer peripheral interfaces needing jitter-reduced clock signals
