SY898530U Product Brief 500MHz 1:16 3.3V-to-2.5V LVPECL Fanout Buffer Description The SY898530U is a 1:16 Fanout buffer which can accept The SY898530U operates from a 3.3V ±5% core power most standard differential logic levels and outputs the supply and a 2.5V ±5% output supply and is guaranteed signal as a differential 2.5V LVPECL signal. The part can over the full commercial temperature range (0°C to amplify input signals as small as 150mVPP to the full +70°C). It is available in a 48-pin TQFP lead-free package. LVPECL output swing. The SY898530U is well suited for Datasheets and support documentation can be found on clock distribution applications, which demand versatility Micrel’s web site at www.micrel.com. and low-skew performance. It is pin-to-pin compatible with IDT’s ICS8530 fanout buffer. ____________________________________________________________________________________________________________ Functional Block Diagram Micrel, Inc.
