DSC400-1133Q0079
Crystal-less™ Configurable Clock Generator
General Description
The DSC400-1133Q0079 is a four output
crystal-less™ clock generator. It utilizes Micrel's
proven PureSilicon™ MEMS technology to provide
excellent jitter and stability while incorporating
additional device functionality.
The frequencies of the outputs can be identical or
independently derived from two shared PLLs. Each
output may be configured independently to support
LVCMOS, LVPECL, LVDS, or HCSL output
standards.
The DSC400-1133Q0079 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.
Features
• Frequencies and output formats:
- 100MHz LVDS x 2
- 66.666666MHz LVCMOS x 1
- 25MHz LVCMOS x 1
• Low RMS phase jitter: <1ps (typ)
• High stability: ±25ppm, ±50ppm
• Wide temperature range
