DATASHEET
Dual LVCMOS/LVTTL-To-Differential
2.5V/3.3V LVPECL Translator
ICS85322I
ICS85322I REVISION D MARCH 6, 2014 1 ©2014 Integrated Device Technology, Inc.
General Description
The ICS85322I is a Dual LVCMOS / LVTTL-to- Differential 2.5V / 3.3V
LVPECL translator. The ICS85322I has selectable single ended clock
inputs. 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 or TSSOP package makes this device ideal
for applications where space, high performance and low power are
important.
Features
• Two 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
L
VTTL
• 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
• Lead-free (RoHS 6) packaging
