www.DataSheet4U.com Integrated Circuit Systems, Inc. ICS81006 VCXO-TO-6 LVCMOS OUTPUTS 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 3.3V/3.3V 3.3V/2.5V 3.3V/1.8V 2.5V/2.5V 2.5V/1.8V 4mm x 4mm 20 Lead VFQFN package is ideal for space constrained designs 0°C to 70°C ambient operating temperature Available in both standard and lead-free RoHS compliant packages GENERAL DESCRIPTION The ICS81006 is a high performance, low jitter/low phase noise VCXO and is a HiPerClockS™ member of the HiPerClockS™ family of high performance clock solutions from ICS. The ICS81006 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. IC S 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 - V DD. 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.
