Integrated Circuit Systems, Inc. ICS889874 DIFFERENTIAL-TO-LVPECL BUFFER/DIVIDER The ICS889874 is a high speed 1:2 Differential- to-LVPECL Buffer/Divider and is a member of HiPerClockS the HiPerClockS family of high performance clock solutions from ICS. The ICS889874 has a selectable ÷1, ÷2, ÷4, ÷8, ÷16 output divider, which allows the device to be used as either a 1:2 fanout buffer or frequency divider. The clock input has internal termination resistors, allowing it to interface with several differential signal types while minimizing the number of required external components. The device is packaged in a small, 3mm x 3mm VFQFN package, making it ideal for use on space-constrained boards. • Two LVPECL outputs • Frequency divide select options ÷ 1, ÷ 2, ÷4, ÷8, ÷16 • IN, nIN input can accept the following differential input levels LVPECL, LVDS, CML • Output frequency > 2.5GHz • Output skew 5ps typical • Part-to-part skew TBD • Additive jitter, RMS <0.03ps design target • Supply voltage range LVPECL , 2.375V to 3.465V Supply voltage range ECL , -3.465V to -2.375V • -40°C to 85°C ambient operating temperature • Available in both standard and lead-free RoHS compliant packages BLOCK DIAGRAM nRESET Enable FF Enable S0 Decoder 00 ÷2 01 ÷4 10 ÷8 11 ÷16 PIN ASSIGNMENT Q0 nQ0 16 15 14 13 12 IN nQ0 2 11 VT 1 0 VREF_AC nQ1 4 9 nIN 5678 TABLE ORDERING INFORMATION Part/Order Number Marking Package Shipping Packaging Temperature ICS889874AK 874A 16 Lead VFQFN tube -40°C to 85°C ICS889874AKT 874A 16 Lead VFQFN 2500 tape & reel -40°C to 85°C ICS889874AKLF 16 Lead "Lead-Free" VFQFN tube -40°C to 85°C ICS889874AKLFT 16 Lead "Lead-Free" VFQFN 2500 tape & reel -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.
