DSC400-3333Q0104  
Crystal-less™ Configurable Clock Generator  
General Description  
Features  
The DSC400-3333Q0104 is  
a
four output  
• Frequencies and output formats:  
- 125MHz LVDS x 1  
- 100MHz LVDS x 1  
- 200MHz LVDS x 1  
- 156.25MHz LVDS x 1  
• Low RMS phase jitter: <1ps (typ)  
• High stability: ±50ppm, ±25ppm  
• Wide temperature range  
- Industrial: -40°C to +85°C  
- Ext. commercial: -20°C to +70°C  
crystal-less™ clock generator. It utilizes Microchip'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 DSC400-3333Q0104 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.  
• 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  
Applications  
• Communications and Networks  
• Ethernet  
- 1G, 10GBASE-T/KR/LR/SR, and FCoE  
• 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  
• Storage Area Networks  
- SATA, SAS, Fibre Channel  
• Passive Optical Networks  
- EPON, 10G-EPON, GPON, 10G-GPON  
• HD/SD/SDI Video & Surveillance  
• Automotive  
• Media and Video  
• Embedded and Industrial
