DSC2311
Crystal-less™ Configurable Two Output Clock Generator
General Description
Features
The DSC2311 is a crystal-less clock
generator that is factory configurable to
Two Simultaneous CMOS Outputs:
o Output 1 Range: 2.3 to 170 MHz
simultaneously
output
two
separate
o
Output 2 Range: 2.3 to 170 MHz
frequencies from 2.3 to 170 MHz. The clock
generator uses proven silicon MEMS
technology to provide low jitter and high
frequency stability across a wide range of
Low RMS Phase Jitter: <1 ps (typ)
High Stability: ±25, ±50 ppm
supply voltages and temperatures.
By
Wide Temperature Range
o Automotive: -55° to 125° C
o Ext. Industrial: -40° to 105° C
o Industrial: -40° to 85° C
eliminating the external quartz crystal,
crystal-less clock generators significantly
enhance reliability and accelerate product
development, while meeting stringent clock
performance criteria for a variety of
consumer electronics, communications, and
storage applications.
o Ext. commercial: -20° to 70° C
High Supply Noise Rejection: -50 dBc
High Shock & Vibration Immunity
o Qualified to MIL-STD-883
DSC2311 has an Output Enable / Disable
feature allowing it to disable the outputs
when OE is low. The device is available in a
space saving 6 pin 2.5 x 2.0 mm crystal-
less TDFN package that uses only a single
external bypass capacitor. This requires a
PCB footprint equivalent to that of a 1.0 x
1.0 mm crystal-based clock generator.
High Reliability
o 20x higher MTBF than crystal-based
clock generator designs
Supply Range of 2.25 to 3.6 V
Short Lead Times: 2 Weeks
Lead Free & RoHS Compliant
