DSC2110 DSC2210
Low-Jitter I2C/SPI Programmable CMOS Oscillator
Datasheet
General Description
Features
The DSC2110 and DSC2210 series of
Low RMS Phase Jitter: <1 ps (typ)
High Stability: ±10, ±25, ±50 ppm
programmable,
high-performance
CMOS
oscillators utilize a proven silicon MEMS
technology to provide excellent jitter and
stability while incorporating high output
frequency flexibility and drive strength
control. DSC2110 and DSC2210 allow the
user to modify the frequency and CMOS drive
strength using I2C or SPI interface,
respectively. User can also select from two
pre-programmed default output frequencies
using the control pin.
