DSC400
Configurable Four Output, Low Jitter Crystal-less™ Clock Generator
General Description
The DSC400 is a four output crystal-less™
clock generator. It utilizes Micrel’s proven
PureSiliconMEMS technology to provide
excellent jitter and stability while
incorporating additional device functionality.
The frequencies of the outputs can be
identical or independently derived from
common PLLs.
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.
The DSC400 is packaged in a 20-pin QFN
(5mm x 3.2mm) and is available in extended
commercial and industrial temperature
grades.

Notes:
1. VDD pins should be filtered with a 0.1µF capacitor connected between VDD and VSS.
2. The addition of IDDcore and IDDio provides total current consumption of the device
3. tsu is time to 100 ppm stable output frequency after VDD is applied and outputs are enabled.
4. Output Waveform figures below the parameters. See Output Waveform section
