VCXO-TO-LVCMOS OUTPUTS
ICS81006I
GENERAL DESCRIPTION
The ICS81006I is a high performance, low jitter/
ICS low phase noise VCXO and is a member of the
HiPerClockS™ HiPerClockS™ family of high performance clock
solutions from IDT. 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.
The frequency of the VCXO is adjusted by the VC control
voltage input. The output range is ±100ppm around the
nominal crystal frequency. The VC control voltage range is
0 - VDD. The device is packaged in a small 4mm x 4mm
VFQFN package and is ideal for use on space constrained
boards typically encountered in ADSL/VDSL applications.
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
