DUAL LVCMOS / LVTTL-TO-DIFFERENTIAL

2.5V / 3.3V LVPECL TRANSLATOR

GENERAL DESCRIPTION

ICS

The ICS85322I is a Dual LVCMOS / LVTTL-to-

Differential 2.5V / 3.3V LVPECL translator and a

HiPerClockS™ member of the HiPerClocks™family of High Per-

formance Clocks Solutions from ICS. The

ICS85322I has selectable single ended clock in-

puts. The single ended clock input accepts LVCMOS or LVTTL

input levels and translate them to 2.5V / 3.3V LVPECL levels.

The small outline 8-pin SOIC package makes this device ideal

for applications where space, high performance and low power

are important.

FEATURES

• 2 differential 2.5V/3.3V LVPECL outputs

• Selectable CLK0, CLK1 LVCMOS/LVTTL clock inputs

• CLK0 and CLK1 can accepts the following input levels:

LVCMOS or LVTTL

• Maximum output frequency: 267MHz

• Part-to-part skew: 250ps (maximum)

• 3.3V operating supply voltage

(operating range 3.135V to 3.465V)

• 2.5V operating supply voltage

(operating range 2.375V to 2.625V)

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