DSC2044FE2-H0006

Crystal-less™ Configurable Clock Generator

General Description

Features

The DSC2044FE2-H0006 is a programmable, high

performance dual HCSL output oscillator utilizing

Microchip'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

156.25MHz

- HCSL

156.25MHz

• Low RMS phase jitter: <1ps (typ)

• ±25ppm 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

• High reliability

- 20x better MTF than quartz oscillators

• Supply range of 2.25 to 3.6V

• AEC-Q100 automotive qualified

• 14-pin 3.2mm x 2.5mm QFN package

The DSC2044FE2-H0006 has provision for up to eight

user-defined pre-programmed, pin-selectable output

frequency combinations.
