PRELIMINARY Integrated Circuit Systems, Inc. LOW SKEW, 1-TO-8 CRYSTAL-TO-LVCMOS/LVTTL FANOUT BUFFER Features - 8 LVCMOS/LVTTL outputs (19Ω typical output impedance) - 2 Crystal oscillator input pairs 1 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 d Bc/Hz 1k Hz .............. -139.9 d Bc/Hz 10k Hz .............. -157.3 d Bc/Hz 100k Hz .............. -157.5 d Bc/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 - 0°C to 70°C ambient operating temperature - Industrial temperature available upon request GENERAL DESCRIPTION The ICS83908-02 is a low skew, high performance 1-to-8 Crystal Oscillator/3.3V LVCMOS-to-3.3V Hi Per Clock S™ LVCMOS fanout buffer and a member of the Hi Per Clock S™ family of High Performance Clock Solutions from ICS. The ICS83908-02 has selectable single ended clock or two crystal-oscillator inputs. There is an output enable to disable the outputs by placing them into a high-impedance state. .. Guaranteed output and part-to-part skew characteristics make the ICS83908-02 ideal for those applications demanding well defined performance and repeatability.
