ESCRIPTION
The ICS87321I is a high perfor mance ÷1, ÷2
Differential-to-LVPECL Clock Generator and a mem-
HiPerClockS™
ber of the HiPerClockS™ family of High Performance
Clock Solutions from IDT. The CLK, nCLK pair can
accept most standard differential input levels. The
ICS87321I is characterized to operate from a 3.3V or 2.5V power
supply. Guaranteed part-to-part skew characteristics make the
ICS87321I ideal for those clock distribution applications demand-
ing well defined performance and repeatability.
F
EATURES
• One differential LVPECL output
• One CLK, nCLK input pair
• CLK, nCLK pair can accept the following differential
input levels: LVPECL, LVDS, LVHSTL, SSTL, HCSL
• Maximum clock input frequency: 700MHz
• Translates any single ended input signal (LVCMOS, LVTTL,
GTL) to LVPECL levels with resistor bias on nCLK input
• Part-to-part skew: 600ps (maximum)
• Propagation delay: 1.8ns (maximum)
• Additive phase Jitter, RMS: 0.18ps
• Full 3.3V or 2.5V operating supply
• -40°C to 85°C ambient operating temperature
• Available in both standard (RoHS 5) and lead-free (RoHS 6)
