Integrated Circuit Systems, Inc. LOW SKEW, 1:6 CRYSTAL INTERFACE-TOLVCMOS / LVTTL FANOUT BUFFER Features - 6 LVCMOS / LVTTL outputs - Outputs able to drive 12 series terminated lines - Crystal oscillator interface - Crystal input frequency range: 10MHz to 40MHz - Output skew: 80ps (maximum) - RMS phase jitter @ 25MHz, (100Hz - 1MHz): 0.26ps (typical) (VDD = VDDO = 2.5V) Phase noise: Offset Noise Power 100Hz .............. -129.7 d Bc/Hz 1k Hz .............. -144.4 d Bc/Hz 10k Hz .............. -147.3 d Bc/Hz 100k Hz .............. -157.3 d Bc/Hz - 5V tolerant enable inputs - Synchronous output enables - Operating power supply modes: Full 3.3V, 2.5V and 1.8V, mixed 3.3V core/2.5V output operating supply, mixed 3.3V core/1.8V output operating supply, mixed 2.5V core/1.8V output operating supply - -40°C to 85°C ambient operating temperature - Lead-Free package fully Ro HS pliant GENERAL DESCRIPTION The ICS83905I is a low skew, 1-to-6 LVCMOS / LVTTL Fanout Buffer and a member of the Hi Per Clock S™ Hi Per Clock S™ family of High Performance Clock Solutions from ICS. The low impedance LVCMOS/LVTTL outputs are designed to drive 50W series or parallel terminated transmission lines. The effective fanout can be increased from 6 to 12 by utilizing the ability of the outputs to drive two series terminated lines. .. The ICS83905I is characterized at full 3.3V, 2.5V, and 1.8V, mixed 3.3V/2.5V, 3.3V/1.8V and 2.5V/1.8V output operating supply mode. Guaranteed output and part-to-part skew characteristics along with the 1.8V output capabilities makes the ICS83905I ideal for high performance, single ended applications that also require a limited output voltage.
