ICS87946AYI-01 REV. BMAY 4, 2007
Description
The ICS87946I-01 is a low skew, ÷1, ÷2 Clock
Generator and a member of the HiPerClockS
family of High Performance Clock Solutions from
IDT. The ICS87946I-01 has one LVPECL clock input
pair. The PCLK/PCLK pair can accept LVPECL,
CML, or SSTL input levels. The low impedance LVCMOS/LVTTL
outputs are designed to drive 50
series or parallel terminated
transmission lines. The effective fanout can be increased from 10
to 20 by utilizing the ability of the outputs to drive two series
terminated lines.
The divide select inputs, DIV_SELx, control the output frequency
of each bank. The outputs can be utilized in the ÷1, ÷2 or a
combination of ÷1 and ÷2 modes. The master reset input, MR/OE,
resets the internal frequency dividers and also controls the active
and high impedance states of all outputs.
The ICS87946I-01 is characterized at 3.3V core/3.3V output and
3.3V core/2.5V output. Guaranteed bank, output and part-to-part
skew characteristics make the ICS87946I-01 ideal for those clock
distribution applications demanding well defined performance and
repeatability.
