GENERAL DESCRIPTION
FEATURES
The ICS85301 is a high performance 2:1 Differ- • 2:1 LVPECL MUX
ICS
HiPerClockS™
ential-to-LVPECL Multiplexer and a member of the
• One LVPECL output
HiPerClockS™family of High Performance Clock
Solutions from ICS.The ICS85301 can also per-
form differential translation because the differ-
• Two differential clock inputs can accept: LVPECL, LVDS,
CML
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.
• 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
