ICS840001
FEMTOCLOCKSCRYSTAL-TO-
LVCMOS/LVTTL CLOCK GENERATOR
GENERAL DESCRIPTION
The ICS840001 is a Fibre Channel Clock
Generator and a member of the HiPerClocksTM
family of high performance devices from ICS. The
ICS840001 uses a 26.5625MHz crystal to
synthesize either 106.25MHz or 212.5MHz, using
the FREQ_SEL pin. The ICS840001 has excellent phase jitter
performance, over the 637KHz – 10MHz integration range.
The ICS840001 is packaged in a small 8-pin TSSOP, making
it ideal for use in systems with limited board space.
FEATURES
1 LVCMOS/LVTTL output, 7 typical output impedence
Crystal oscillator interface designed for 26.5625MHz,
18pF parallel resonant crystal
Selectable 106.25MHz or 212.5MHz output frequency
VCO range: 560MHz to 680MHz
RMS phase jitter @ 106.25MHz, using a 26.5625MHz crystal
(637KHz - 10MHz): 0.696ps (typical)
RMS phase noise at 106.25MHz (typical)
Phase noise:
