ICS85301

2:1

The ICS85301 is a high performance 2:1 Differ-

ential-to-LVPECL Multiplexer and a member of the

HiPerClockS™family of High Performance Clock

Solutions from ICS. The ICS85301 can also per-

form differential translation because the differ-

ential inputs accept LVPECL, CML as well as LVDS levels.

The ICS85301 is packaged in a small 3mm x 3mm

16 VFQFN package, making it ideal for use on space con-

strained boards.

• 2:1 LVPECL MUX

• One LVPECL output

• Two differential clock inputs can accept: LVPECL, LVDS,

CML

• Maximum input/output frequency: 3GHz

• Translates LVCMOS/LVTTL input signals to LVPECL levels

by using a resistor bias network on nPCLK0, nPCLK0

• Propagation delay: 490ps (maximum)

• Part-to-part skew: 150ps (maximum)

• Additive phase jitter, RMS: 0.009ps (typical)

• Full 3.3V or 2.5V operating supply

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

• Available in both standard and lead-free RoHS compliant
