Product Overview NB3L553: Clock / Data Fanout Buffer, 2.5 V / 3.3 V / 5.0 V 1:4 For complete documentation, see the data sheet Product Description The NB3L553 is a low skew 1-to-4 clock fanout buffer, designed for clock distribution in mind. The NB3L553 specifically guarantees low output-to-output skew. Optimal design, layout and processing minimize skew within a device and from device to device. The output enable (OE) pin tri-states the outputs when low. Features Benefits • Input/Output Clock Frequency up to 200 MHz • • • • • • Multiply the low frequency output of inexpensive crystals to the full system frequency • Minimize timing deviations and synchronization issues • Ensures operation in the majority of designs • Small package with robust thermal capability • Meets all green international materials standards Low Skew Ouptuts (35ps) Operating Range: VDD = 2.375 V to 5.25V Full Industrial Temperature Range 8-pin SOIC Full RoHS certification Output Enable puts device in three-state mode Applications • Clock fan out in routers, switches and other networking applications Part Electrical Specifications Product Compliance Status Type Chann els Input / Input Output Level Ratio NB3L553DG Pb-free Active Buffer 1 1:4 Output VCC Level Typ (V) CMOS CMOS Halide free tJitterR MS Typ (ps) tskew(oo) Max (ps) tpd Typ (ns) tR & tF Max (ps) fmaxClo fmaxDat Packa ck Typ a Typ ge (MHz) (Mbps) Type 2.5 0.029 50 2.5 0.001 200 5 0.018 3 0.001 5 SOIC8 200 SOIC8 200 DFN-8 3.3 2.4 0.000 7 NB3L553DR2G Pb-free Active Buffer 1 1:4 CMOS CMOS Halide free 5 0.018 3.3 0.029 50 2.5 2.4 2.5 3 0.001 5 0.000 7 0.001 NB3L553MNR4G Pb-free Halide free Active Buffer 1 1:4 CMOS CMOS 3.3 0.029 2.5 0.018 5 50 2.4 3 2.5 0.001 5 0.000 7 0.001 For more information please contact your local sales support at www.onsemi.com Created on: 6/30/2016
