ICS83904-02 Datasheet | Integrated Device Technology

LOW SKEW, 1-TO-4, CRYSTAL-TOLVCMOS/LVTTL FANOUT BUFFER GENERAL DESCRIPTION The ICS83904-02 is a low skew, high perfor IC S mance 1-to-4 Crystal Oscillator/Crystal-to-LVCMOS Hi Per Clock S™ Fanout Buffer and a member of the Hi Per Clock S™ family of High Performance Clock Solutions from IDT. The ICS83904-02 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 par t-to-par t skew characteristics Features - Four LVCMOS/LVTTL outputs, 19Ω typical output impedance @ VDD = VDDO = 3.3V - Two Crystal oscillator input pairs One LVCMOS/LVTTL clock input - Crystal input frequencry range: 12MHz - 38.88MHz - Output frequency: 200MHz (maximum) - Output Skew: 40ps (maximum) @ VDD = VDDO = 3.3V - RMS phase jitter @ 25MHz output, using a 25MHz crystal (100Hz - 1MHz): 0.16ps (typical) @ VDD = VDDO = 3.3V - RMS phase noise at 25MHz: Offset Noise Power 100Hz ............. -118.4 d Bc/Hz 1k Hz ............. -141.5 d Bc/Hz 10k Hz ............. -157.2 d Bc/Hz 100k Hz ............. -157.2 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 make the ICS83904-02 ideal for those applications demanding well defined performance and repeatability.
