DSC400  
Configurable Four Output, Low Jitter Crystal-less™ Clock Generator  
Features  
General Description  
Low RMS Phase Jitter: <1 ps (typ)  
The DSC400 is a four output crystal-less™  
High Stability: ±25ppm, ±50ppm  
clock generator. It utilizes Micrel’s proven  
PureSiliconMEMS technology to provide  
Wide Temperature Range  
o Ext. commercial: -20°C to 70°C  
o Industrial: -40°C to 85°C  
excellent  
jitter  
and  
stability  
while  
incorporating additional device functionality.  
The frequencies of the outputs can be  
identical or independently derived from  
common PLLs.  
High Supply Noise Rejection: -50 dBc  
Four format configurable outputs:  
o LVPECL, LVDS, HCSL, LVCMOS  
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.  
Available Pin-Selectable frequency table  
o 1 pin per bank for 2 frequency sets  
Wide Freq. Range:  
o 2.3 MHz 460 MHz  
20 QFN Footprint (5mm x 3.2mm)  
Excellent Shock & Vibration Immunity  
o Qualified to MIL-STD-883  
The DSC400 is packaged in a 20-pin QFN  
(5mm x 3.2mm) and is available in extended  
High Reliability  
o 20x better MTF than quartz based devices  
commercial and  
industrial  
temperature  
Wide Supply Range of 2.25 to 3.6 V  
Lead Free & RoHS Compliant  
grades.  
AEC-Q100 Automotive Qualified
