FEATURES:
• Four differential 3.3V LVPECL outputs
• Selectable CLK0 or CLK1 inputs for redundant and multiple
frequency fanout applications
• Maximum output frequency: 266MHz
• CLK0 or CLK1 can accept LVCMOS or LVTTL input levels
• Translates LVCMOS and LVTTL levels to 3.3V LVPECL levels
• Output skew: 30ps (max.)
• Part-to-part skew: as low as 150ps
• Propagation delay: 1.9ns (max.)
• 3.3V operating supply
• Available in TSSOP package
DESCRIPTION:
The IDT8535-01 is a low skew, high performance 1-to-4 LVCMOS-to-3.3V
LVPECL fanout buffer. It has two single-ended clock inputs. The single-ended
clock input accepts LVCMOS or LVTTL input levels and translates them to 3.3V
LVPECL levels. The clock 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 IDT8535-
01 ideal for those applications demanding well-defined performance and
repeatability.
