LOW SKEW, 1-TO-4 DIFFERENTIAL-TO-CML FANOUT BUFFER ICS858020 The ICS858020 is a high speed 1-to-4 Differential-to-Open-Collector Output Fanout Buffer HiPerClockS and is a member of the HiPerClockS family of high performance clock solutions from IDT. The ICS858020 uses an open-collector output structure which requires the termination of the output by to VCC. The ICS858020 is optimized for high speed and very low output skew, making it suitable for use in demanding applications such as SONET, 1 Gigabit and 10 Gigabit Ethernet, and Fibre Channel. The internally terminated differential input and VREF_AC pin allow other differential signal families such as LVDS, LVHSTL and Open Collector Output OC to be easily interfaced to the input with minimal use of external components. The ICS858020 is packaged in a small 3mm x 3mm 16-pin VFQFN package which makes it ideal for use in space-constrained applications. • Four differential CML outputs • One LVPECL differential clock input • IN/nIN pair can accept the following differential input levels: LVPECL, LVDS, CML, SSTL • Maximum output frequency 3.2GHz • Output skew 30ps maximum • Part-to-part skew 225ps maximum • Additive phase jitter, RMS <0.3ps typical • Propagation delay 600ps maximum • Operating voltage supply range: VCC = 2.375V to 3.63V, VEE = 0V • -40°C to 85°C ambient operating temperature • Available in both standard RoHS 5 and lead-free RoHS 6 packages Block Diagram IN VT nIN VREF_AC Pin Assignment VEE Q0 nQ0 VCC 16 15 14 13 12 Q1 11 nQ1 Q1 nQ1 VREF_AC 3 10 Q2 nIN 4 9 nQ2 5 6 78 VEE nQ3 Q3 VCC ICS858020 16-Lead VFQFN 3mm x 3mm x 0.925mm package body K Package Top View Ordering Information Table Ordering Information Part/Order Number 858020AK 858020AKT 858020AKLF 858020AKLFT Marking 020A 20AL Package 16 Lead VFQFN 16 Lead VFQFN “Lead-Free” 16 Lead VFQFN “Lead-Free” 16 Lead VFQFN Shipping Packaging Tube 2500 Tape & Reel Tube 2500 Tape & Reel Temperature -40°C to 85°C -40°C to 85°C -40°C to 85°C -40°C to 85°C NOTE Parts that are ordered with an "LF" suffix to the part number are the Pb-Free configuration and are RoHS compliant.

LOW SKEW, 1-TO-4 DIFFERENTIAL-TO-CML FANOUT BUFFER

ICS858020

The ICS858020 is a high speed 1-to-4

Differential-to-Open-Collector Output Fanout Buffer

HiPerClockS and is a member of the HiPerClockS family of
high performance clock solutions from IDT. The

ICS858020 uses an open-collector output structure
which requires the termination of the output by to VCC. The ICS858020 is optimized for high speed and very low output skew,
making it suitable for use in demanding applications such as
