ICS85314I-01
LOW SKEW, 1-TO-5
DIFFERENTIAL-TO-2.5V/3.3V LVPECL FANOUT BUFFER
GENERAL DESCRIPTION
FEATURES
The ICS85314I-01 is a low skew, high perfor- 5 differential 2.5V/3.3V LVPECL outputs
ICS
HiPerClockS™
mance 1-to-5 Differential-to-2.5V/3.3V LVPECL
Fanout Buffer and a member of the HiPerClockS™
Selectable differential CLK0, nCLK0 or LVCMOS inputs
family of High Performance Clock Solutions from CLK0, nCLK0 pair can accept the following differential
ICS. The ICS85314I-01 has two selectable clock input levels: LVPECL, LVDS, LVHSTL, HCSL, SSTL
inputs. The CLK0, nCLK0 pair can accept most standard
differential input levels. The single-ended CLK1 can accept
LVCMOS or LVTTL input levels. The clock enable is internally
synchronized to eliminate runt clock pulses on the outputs
CLK1 can accept the following input levels:
LVCMOS or LVTTL
Maximum output frequency: 700MHz
during asynchronous assertion/deassertion of the clock Translates any single-ended input signal to 3.3V
enable pin.
LVPECL levels with resistor bias on nCLK input
Guaranteed output and part-to-part skew characteristics
make the ICS85314I-01 ideal for those applications demand-
ing well defined performance and repeatability.
Output skew: 30ps (maximum), TSSOP package
50ps (maximum), SOIC package
Part-to-part skew: 350ps (maximum)
Propagation delay: 1.8ns (maximum)
RMS phase jitter @ 155.52MHz (12kHz - 20MHz):
0.05ps (typical)
LVPECL mode operating voltage supply range:
V = 2.375V to 3.8V, V = 0V
CC EE
-40°C to 85°C ambient operating temperature
Available in both standard and lead-free RoHS-compliant
packages
