DUAL LVCMOS / LVTTL-TO-
DIFFERENTIAL LVHSTL TRANSLATOR
GENERAL DESCRIPTION
The ICS85222 is a Dual LVCMOS / LVTTL-to-
ICS
Differential LVHSTL Translator and a member of
HiPerClockS™ _{the HiPerClocks™ family of High Performance}
Clock Solutions from ICS. The ICS85222 has two
single ended clock inputs. The single ended clock
input accepts LVCMOS or LVTTL input levels and translates
them to LVHSTL levels. The small outline 8-pin SOIC pack-
age makes this device ideal for applications where space,
high performance and low power are important. For optimum
performance, both output pairs need to be terminated, even if
one output pair is unused.
FEATURES
• 2 differential LVHSTL outputs
• Selectable CLK0, CLK1 LVCMOS clock inputs
• CLK0 and CLK1 can accept the following input levels:
LVCMOS or LVTTL
• Maximum output frequency: 350MHz
• Part-to-part skew: 350ps (maximum)
• Propagation delay: 1.3ns (maximum)
• V_OH: 1.2V (maximum)
• 3.3V and 2.5V operating supply
• 0°C to 70°C ambient operating temperature
• Industrial temperature information available upon request
• Lead-Free package fully RoHS compliant
