GENERAL DESCRIPTION

The ICS853111A is a low skew, high performance 1-to-10 Differential-to-2.5V/3.3V LVPECL/ECL Fanout Buffer and a member of the HiPerClockS ™ family of High Performance Clock Solutions from IDT. The ICS853111A is characterized to operate from either a 2.5V, 3.3V or a 5V power supply. Guaranteed output and part-to-part skew characteristics make the ICS853111A ideal for those clock distribution applications demanding well defined performance and repeatability.

FEATURES

• Ten differential LVPECL outputs

• Two selectable differential LVPECL PCLK/nPCLK clock inputs

• PCLK, nPCLK pairs can accept the following differential input levels: LVPECL, LVDS, CML, SSTL

• Maximum output frequency: >3GHz

• Translates any single ended input signal to 3.3V LVPECL levels with resistor bias on nPCLK input

• Additive phase jitter, RMS: <0.3ps (typical)

• Output skew: 23ps (typical)

• Part-to-part skew: 85ps (typical)

• Propagation delay: 705ps (typical)

• LVPECL mode operating voltage supply range:

VCC = 2.375V to 5.25V, VEE = 0V

• 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
