DSC400-0101Q0082
Crystal-less™ Configurable Clock Generator
General Description
The DSC400-0101Q0082 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 DSC400-0101Q0082 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:
- 22.5792MHz LVCMOS x 1
- 24.576MHz LVCMOS x 1
• Low RMS phase jitter: <1ps (typ)
• High stability: ±25ppm, ±50ppm
• Wide temperature range
- Industrial: -40°C to +85°C
- Ext. commercial: -20°C to +70°C
• High supply noise rejection: -50dBc
• Available pin-selectable frequency table
- 1 pin per bank for 2 frequency sets
• Excellent shock & vibration immunity
- Qualified to MIL-STD-883
• High reliability
- 20x better MTF than quartz based devices
• Supply range of 2.25V to 3.6V
• AEC-Q100 automotive qualified
• 20-pin 5mm x 3.2mm QFN package
Applications
