FEMTOCLOCKS™CRYSTAL-TO-3.3V, 2.5V
LVPECL CLOCK GENERATOR
GENERAL DESCRIPTION
The ICS843023I is a Gigabit Ethernet Clock
ICS Generator and a member of the HiPerClocksTM
HiPerClockS™ family of high performance devices from ICS.
The ICS843023I uses a 25MHz crystal to
synthesize 250MHz. The ICS843023I has
excellent phase jitter performance, over the 1.875MHz – 20MHz
integration range. The ICS843023I is packaged in a small
8-pin TSSOP, making it ideal for use in systems with
limited board space.
FEATURES
• 1 differential 3.3V LVPECL output
• Crystal oscillator interface designed for 25MHz,
18pF parallel resonant crystal
• Output frequency range: 245MHz - 320MHz
• VCO range: 490MHz - 640MHz
• RMS phase jitter @ 250MHz, using a 25MHz crystal
(1.875MHz - 20MHz): 0.39ps (typical)
Phase noise:
Offset
