ICS843321AGI-12 REV. A FEBRUARY 27, 2009
General Description
The ICS843321I-12 is a SONET Clock Generator
and a member of the HiPerClocksTM family of high
performance devices from IDT. The ICS843321I-12
can synthesize SONET reference clock frequencies
with the appropriate choice of crystal and output
divider. The ICS843321I-12 uses IDT’s 3rd generation low phase
noise VCO technology, and can achieve <1ps rms phase jitter
performance over the 12kHz – 20MHz integration range. The
ICS843321I-12 is packaged in a small 8-pin TSSOP, making it
ideal for use in systems with limited board space.
