DSC2111FI2-E0019

Crystal-less™ Configurable Clock Generator

General Description

Features

The DSC2111FI2-E0019 is a programmable, high

performance dual LVCMOS output oscillator utilizing

Micrel's proven silicon MEMS technology to provide

excellent jitter and stability while incorporating

high output frequency flexibility and drive strength

control.

The DSC2111FI2-E0019 allows the user to

independently modify the frequency of each output

and LVCMOS drive strength using I2C interface.

• Frequency and output formats:

- LVCMOS

74.25/74.25MHz

- LVCMOS

148.5/148.5MHz

• Low RMS phase jitter: <1ps (typ)

• ±25ppm frequency stability

• -40°C to +85°C industrial temperature range

• High supply noise rejection: -50dBc

• I2C programmable frequency and drive

• Excellent shock & vibration immunity

- Qualified to MIL-STD-883

• High reliability

The user can also select from two pre-programmed

default output frequencies using the frequency

select pin.

Applications

- 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

• Consumer Electronics

• Storage Area Networks

- SATA, SAS, Fibre Channel

• Passive Optical Networks

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

• Ethernet

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