GENERAL DESCRIPTION

The ICS853017 is a quad 1-to-1, 2.5V/3.3V/5V differential LVPECL/ECL receiver and a member of the HiperclocksTM family of High Performance Clock Solutions from IDT. The ICS853017 operates with a positive or negative power supply at 2.5V, 3.3V or 5V, and can accept both single-ended and differential inputs. For single ended operation, an internally generated voltage, which is avail able on output pin VBB, can be used as a switching bias voltage on the unused input of the differential pair. VBB can also be used to rebias AC coupled inputs.

FEATURES

• Four differential LVPECL / ECL 1:1 receivers

• Four differential LVPECL clock input pairs

• PCLKx, nPCLKx pairs can accept the following differential input levels: LVPECL, LVDS, CML, SSTL

• Output frequency: >2GHz (typical)

• Translates any single ended input signal to LVPECL levels with resistor bias on nPCLKx input

• Output skew: TBD

• Part-to-part skew: TBD

• Propagation delay: 320ps (typical)

• LVPECL mode operating voltage supply range:

   VCC = 2.375V to 5.25V

• ECL mode operating voltage supply range:

   VCC = 0V, VEE = -5.25V to -2.375V

• -40°C to 85°C ambient operating temperature

• Available in both standard (RoHS 5) and lead-free (RoHS 6) packages
