DSC2311
Crystal-less™ Configurable Two Output Clock Generator
General Description
The DSC2311 is a crystal-less clock
generator that is factory configurable to
simultaneously output two separate
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
supply voltages and temperatures. By
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.
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.
Features
Two Simultaneous CMOS Outputs:
o Output 1 Range: 2.3 to 170 MHz
o Output 2 Range: 2.3 to 170 MHz
