ICS85222-01
DUAL LVCMOS / LVTTL-TO-
DIFFERENTIAL HSTL TRANSLATOR
GENERAL DESCRIPTION
The ICS85222-01 is a Dual LVCMOS / LVTTL-
to-Differential HSTL translator and a member of
the HiPerClocks™ fa m i l y o f H i g h Pe r fo r mance
Clock Solutions from ICS. The ICS85222-01 has
two single ended clock inputs. The single ended
clock input accepts LVCMOS or LVTTL input levels and trans-
lates them to HSTL levels. The small outline 8-pin SOIC pack-
age makes this device ideal for applications where space,
high performance and low power are important.
FEATURES
• Two differential HSTL outputs
• CLK0, CLK1 LVCMOS/LVTTL clock inputs
• CLK0 and CLK1 can accept the following input levels:
LVCMOS or LVTTL
• Maximum output frequency: 350MHz
• Part-to-part skew: 375ps (maximum)
• Propagation delay: 1075ps (maximum)
• V
OH
: 1.4V (maximum)
• Full 3.3V and 2.5V operating supply voltage
• 0°C to 70°C ambient operating temperature
• Industrial temperature information available upon request
• Available in both standard and lead-free RoHS-compliant
packages
