DSC400

Configurable Four Output, Low Jitter Crystal-less™ Clock Generator

Features

General Description

 Low RMS Phase Jitter: <1 ps (typ)

The DSC400 is a four output crystal-less™

 High Stability: ±25ppm, ±50ppm

clock generator. It utilizes Micrel’s proven

PureSilicon™ MEMS technology to provide

 Wide Temperature Range

o Ext. commercial: -20°C to 70°C

o Industrial: -40°C to 85°C

excellent

jitter

and

stability

while

incorporating additional device functionality.

The frequencies of the outputs can be

identical or independently derived from

common PLLs.

 High Supply Noise Rejection: -50 dBc

 Four format configurable outputs:

o LVPECL, LVDS, HCSL, LVCMOS

Each

output

may

configured

independently to support a single ended

LVCMOS interface or a differential interface.

Differential options include LVPECL, LVDS, or

HCSL.

The DSC400 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.

 Available Pin-Selectable frequency table

o 1 pin per bank for 2 frequency sets

 Wide Freq. Range:

o 2.3 MHz – 460 MHz

 20 QFN Footprint (5mm x 3.2mm)

 Excellent Shock & Vibration Immunity

o Qualified to MIL-STD-883

The DSC400 is packaged in a 20-pin QFN

(5mm x 3.2mm) and is available in extended

 High Reliability

o 20x better MTF than quartz based devices

commercial and

industrial

temperature

 Wide Supply Range of 2.25 to 3.6 V

 Lead Free & RoHS Compliant

grades.

 AEC-Q100 Automotive Qualified

Block Diagram

Applications

 Communications and Networks

 Ethernet

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

 Storage Area Networks

o SATA, SAS, Fibre Channel

 Passive Optical Networks

o EPON, 10G-EPON, GPON, 10G-PON

 HD/SD/SDI Video & Surveillance
