ICS81006I

www.DataSheet4U.com VCXO-TO-LVCMOS OUTPUTS ICS81006I GENERAL DESCRIPTION The ICS81006I is a high performance, low jitter/ IC S 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 - 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. 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 -40°C to 85°C ambient operating temperature Available in both standard (RoHS 5) and lead-free (RoHS 6) packages BLOCK DIAGRAM OE0 (Pullup) PIN ASSIGNMENT GND VDDO OE0 SYNC Q0 VC LP Filter XTAL_IN XTAL_OUT ...
