ICS85322
DUAL LVCMOS / LVTTL-TO-DIFFERENTIAL
2.5V / 3.3V LVPECL TRANSLATOR
GENERAL DESCRIPTION
,&6
HiPerClockS™
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.
The ICS85322 is a Dual LVCMOS / LVTTL-toDifferential 2.5V / 3.3V L VPECL translator and a
member of the HiPerClocks™ family of High Performance Clocks Solutions from ICS. The
ICS85322 has selectable single ended clock in-
FEATURES
• 2 differential 2.5V/3.3V L VPECL outputs
• Selectable CLK0, CLK1 L VCMOS clock inputs
• CLK0 and CLK1 can accepts the following input levels:
LVCMOS or LVTTL
• Maximum output frequency up to 267MHz
• Part-to-part skew: 150ps (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)
• 0°C to 70°C ambient operating temperature
• Industrial temperature information available upon request
