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
