ICS8536I-33 Datasheet, PDF (1/19 Pages) Integrated Device Technology – LOW SKEW, 1-TO-6, CRYSTAL OSCILLATOR/LVCMOSTO-3.3V, 2.5V LVPECL/LVCMOS FANOUT BUFFER

LOW SKEW, 1-TO-6, CRYSTAL OSCILLATOR/LVCMOS-
TO-3.3V, 2.5V LVPECL/LVCMOS FANOUT BUFFER
ICS8536I-33
GENERAL DESCRIPTION
The ICS8536I-33 is a low skew, high performance
ICS
1-to-6 Crystal Oscillator/LVCMOS-to-3.3V, 2.5V
HiPerClockS™ _{LVPECL/LVCMOS fanout buffer and a member of the}
HiPerClockS™ family of High Performance Clock
Solutions from IDT. The ICS8536I-33 has selectable
single ended clock or crystal inputs. The single-ended clock
input accepts LVCMOS or LVTTL input levels and translate
them to 3.3V LVPECL levels. The output enable is internally
synchronized to eliminate runt pulses on the outputs during
asynchronous assertion/deassertion of the clock enable pin.
Guaranteed output and part-to-part skew characteristics make
the ICS8536I-33 ideal for those applications demanding well
defined performance and repeatability.
FEATURES
• Three differential LVPECL outputs, and
three single ended LVCMOS outputs
• Selectable LVCMOS/LVTTL CLK or crystal inputs
• CLK can accept the following input levels: LVCMOS, LVTTL
• Crystal frequency: 25MHz
• Maximum output frequency: 266MHz
• Output skew: 80ps (maximum)
• Part-to-part skew: 800ps (maximum)
• Propagation delay: 1.95ns (maximum)
• Additive phase jitter, RMS: 0.32ps (typical), LVPECL output
• Full 3.3V or 2.5V operating supply
• -40°C to 85°C ambient operating temperature
• Available in both standard (RoHS 5) and lead-free (RoHS 6)
