SM843001-212

ClockWorks^TMFibre Channel, 212.5MHz,

Ultra-Low Jitter LVPECL Clock Frequency

Synthesizer

General Description

Features

The SM843001-212 is a Fibre Channel, 212.5MHz

LVPECL clock frequency synthesizer and a member of the

ClockWorks™ family of devices from Micrel. It provides a

low-noise timing solution for high-speed, high-accuracy

synthesis of clock signals. It includes a patented

RotaryWave^®architecture that provides a stable clock with

very low phase noise.

• Generates a low jitter LVPECL output

• 2.5V or 3.3V operating voltage

• Typical phase jitter ~170fs

(637kHz to 10MHz) @212.5MHz

• Crystal frequency: 26.5625MHz

• 212.5MHz output frequency

• RMS Phase Noise @ 212.5MHz:

Power supplies of either 2.5V or 3.3V are supported, with

superior jitter and phase noise performance. The device

synthesizes a 212.5MHz, low-noise, LVPECL output for

Fibre Channel applications. The crystal reference

frequency used is 26.5625MHz.

The SM843001-212 is an excellent replacement for IDT

FemtoClocks®, with improved waveform integrity, and

jitter.

• Industrial temperature range

• Green, RoHS-, and PFOS-compliant

• Available in 8-pin TSSOP
