FEATURES

GENERAL DESCRIPTION

• Fully integrated PLL

The ICS87951I is a low voltage, low skew 1-to-9

Differential-to-LVCMOS/LVTTL Cock Generator

and a member of the HiPerClockS™ family of High

• 9 single ended 3.3V LVCMOS/LVTTLoutputs

HiPerClockS™

Performance Clock Solutions from ICS. The • Selectable single ended CLK0 or differential

ICS87951I has two selectable clock inputs. The

CLK1, nCLK1 inputs

single ended clock input accepts LVCMOS or LVTTL input

levels. The CLK1, nCLK1 pair can accept most standard differ-

ential input levels. With output frequencies up to 180MHz, the

ICS87951I is targeted for high performance clock applications.

Along with a fully integrated PLL, the ICS87951I contains fre-

quency configurable outputs and an external feedback input for

regenerating clocks with “zero delay”.

• The single ended CLK0 input can accept the following

input levels: LVCMOS or LVTTL input levels

• CLK1, nCLK1 supports the following input types:

LVDS, LVPECL, LVHSTL, SSTL, HCSL

• Output frequency range: 25MHz to 180MHz

• VCO range: 200MHz to 480MHz

• External feedback for ”zero delay” clock regeneration

• Cycle-to-cycle jitter: ±100ps (typical)

• Output skew: 375ps (maximum)

• PLL reference zero delay: 350ps window (maximum)

• 3.3V operating supply

• -40°C to 85°C ambient operating temperature

• Pin compatible with the MPC951
