DSC400

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

Features

General Description

• Low RMS Phase Jitter: <1 ps (typ.)

• High Stability: ±25 ppm, ±50 ppm

• Wide Temperature Range:

The DSC400 is a four output crystal-less™ clock

generator. It utilizes proven PureSilicon™ MEMS

technology to provide excellent jitter and stability while

incorporating additional device functionality.

- Industrial –40°C to +85°C

The nominal frequencies of the outputs can be identical

or independently derived from common PLLs.

- Ext. Commercial –20°C to +70°C

• High Supply Noise Rejection: –50 dBc

• Four Format-Configurable Outputs:

- LVPECL, LVDS, HCSL, LVCMOS

• Available Pin-Selectable Frequency Table

- 1 Pin per Bank for 2 Frequency Sets

• Wide Frequency Range:

Each output may be 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.

- 2.3 MHz – 460 MHz

• 20-Pin QFN Footprint (5.0 mm x 3.2 mm)

• Excellent Shock and Vibration Immunity

• High Reliability

The DSC400 is packaged in a 20-pin QFN (5 mm x

3.2 mm) and is available in extended commercial and

industrial temperature grades.

- 20x better MTF than quartz-based devices

• Wide Supply Range of 2.25V to 3.6V

• Lead Free and RoHS-Compliant

• AEC-Q100 Automotive Qualified
