DSC2044FE1-H0002

Crystal-less™ Configurable Clock Generator

General Description

Features

The DSC2044FE1-H0002 is a programmable, high

performance dual HCSL output oscillator utilizing

Micrel's proven silicon MEMS technology to provide

excellent jitter and stability while incorporating

additional device functionality. Two HCSL outputs

are controlled by separate supply voltages to allow for

high output isolation. The frequencies of the outrputs

can be identical or independently derived from a

common PLL frequency source.

• Frequency and output formats:

- HCSL

200/100/156.25/100/125/125/50/200MHz

- HCSL

100/100/156.25/50/125/50/50/50MHz

• Low RMS phase jitter: <1ps (typ)

• ±50ppm frequency stability

• -20°C to +70°C ext. commercial temperature range

• High supply noise rejection: -50dBc

• Pin-selectable configurations

- Up to 8 output frequency combinations

• Excellent shock & vibration immunity

- Qualified to MIL-STD-883

The DSC2044FE1-H0002 has provision for up to eight

user-defined pre-programmed, pin-selectable output

frequency combinations.
