ICS83908I-02

PRELIMINARY LOW SKEW, 1-TO-8 CRYSTAL-TO-LVCMOS FANOUT BUFFER ICS83908I-02 GENERAL DESCRIPTION The ICS83908I-02 is a low skew, high performance ICS 1-to-8 Crystal Oscillator/3.3V LVCMOS-to-3.3V HiPerClockS™ LVCMOS fanout buffer and a member of the HiPerClockS™ family of High Performance Clock Solutions from IDT. The ICS83908I-02 has selectable single ended clock or two crystal-oscillator inputs. There is an output enable to disable the outputs by placing them into a highimpedance state. www.DataSheet4U.com FEATURES Eight LVCMOS/LVTTL outputs (19Ω typical output impedance) Two Crystal oscillator input pairs One LVCMOS/LVTTL clock input Crystal input frequencry range: 10MHz - 40MHz Output frequency: 200MHz (typical) CLK0 Output Skew: TBD Part to Part Skew: TBD RMS phase jitter @ 25MHz (100Hz - 1MHz): 0.22ps (typical) VDD = VDDO = 3.3V Offset Noise Power 100Hz ............. -111.4 dBc/Hz 1kHz ............. -139.9 dBc/Hz 10kHz ............. -157.3 dBc/Hz 100kHz ............. -157.5 dBc/Hz Supply Voltage Modes: (Core/Output) 3.3V/3.3V 3.3V/2.5V 3.3V/1.8V 2.5V/2.5V 2.5V/1.8V Guaranteed output and part-to-part skew characteristics make the ICS83908I-02 ideal for those applications demanding well defined performance and repeatability.
