GENERAL DESCRIPTION

The ICS81006I is a high performance, low jitter/low phase noise VCXO and is a member of the HiPerClockS™ family of high performance clock solutions from ICS. The ICS81006I works in conjunction with a pullable crystal to generate an output clock over the range of 12MHz - 40MHz and has 6 LVCMOS outputs, effectively integrating a fanout buffer function.

FEATURES

• Six LVCMOS/LVTTL outputs, 20Ω nominal output impedance

• Output Q5 can be selected for ÷1 or ÷2 frequency relative to the crystal frequency

• Output frequency range: 12MHz to 40MHz

• Crystal pull range: ± 90ppm (typical)

• Synchronous output enable places outputs in High-Z state

• On-chip filter on VIN to suppress noise modulation of VCXO

• VDD/VDDO combinations
