Crystal-less™ Configurable Clock Generator

General Description

Features

The DSC400-3333Q0078 is

four output

• Frequencies and output formats:

- 125MHz LVDS x 4

• Low RMS phase jitter: <1ps (typ)

• High stability: ±25ppm, ±50ppm

• Wide temperature range

crystal-less™ clock generator. It utilizes Micrel's

proven PureSilicon™ MEMS technology to provide

excellent jitter and stability while incorporating

additional device functionality.

The frequencies of the outputs can be identical or

independently derived from two shared PLLs. Each

output may be configured independently to support

LVCMOS, LVPECL, LVDS, or HCSL output

standards.

The DSC400-3333Q0078 provides two independent

select lines for choosing between two sets of pre-

configured frequencies per bank. It also has two OE

pins to allow for enabling and disabling outputs.

- Industrial: -40°C to +85°C

- Ext. commercial: -20°C to +70°C

• High supply noise rejection: -50dBc

• Available pin-selectable frequency table

- 1 pin per bank for 2 frequency sets

• Excellent shock & vibration immunity

- Qualified to MIL-STD-883

• High reliability

- 20x better MTF than quartz based devices

• Supply range of 2.25V to 3.6V

• AEC-Q100 automotive qualified

• 20-pin 5mm x 3.2mm QFN package

Applications

• Communications and Networks

• Ethernet

- 1G, 10GBASE-T/KR/LR/SR, and FCoE

• Storage Area Networks

- SATA, SAS, Fibre Channel

• Passive Optical Networks

- EPON, 10G-EPON, GPON, 10G-GPON

• HD/SD/SDI Video & Surveillance

• Automotive

• Media and Video

• Embedded and Industrial
