Product Overview NB4L7210: Clock Driver, 2.5 V / 3.3 V Differential 2x10 Crosspoint, with SDI Programmable Output Selects For complete documentation, see the data sheet Product Description The NB4L7210 is a Clock input crosspoint fanout distribution device selecting between one of two input clocks on each of the 10 differential output pairs. A 10 Bit Serial Data Interface programs each output MUX to asynchronously select either Input clock. CLOCK inputs can accept LVCMOS, LVTTL, LVPECL, CML, or LVDS signal levels and incorporate an internal 50 ohms on die termination resistors. SCLK, SDATA, and SLOAD input can accept single ended LVPECL, CML, LVCMOS, LVTTL signals levels. SCLK and SDATA inputs operate up to 20 MHz. SLOAD input loads and latches the output select data. The SDATAOUT pin permits cascading multiple devices. Outputs are optimized for minimal output-to-output skew and low jitter Features Benefits • • • • • • • Typical Input Clock Frequency > 2 GHz 200 ps Typical Rise and Fall Times 800 ps Typical Propagation Delay Output to Output Skew 150 ps 2 ps RMS Typical Additive Clock Jitter Operating Range: VCC = 2.375 V to 3.6 V with VEE = 0 V Differential LVPECL Output Level (Typ 700 mV Peak-toPeak) • Low Profile 8x8 mm, 52 QFN Package • High Frequency • Critical Edge Placement Applications End Products • WAN: 161.13 MHz / 667 MHz • LAN: 155.52 MHz / 622.08 MHz • Servers Part Electrical Specifications Product Compliance Status Input/Out Channel put Ratio s Input Level Output Level VCC Typ (V) fMax Typ (MHz) NB4L7210MNG Pb-free Active 2:10 CML ECL 3.3 ECL 3.3 1 Halide free tJitter Typ (ps) tskew(OO) Max (ps) tpd Typ (ns) Package Type 1000 35 725 QFN-52 1000 35 725 QFN-52 ECL LVDS CMOS TTL NB4L7210MNTXG Pb-free Halide free Active 2:10 1 CML LVDS CMOS TTL ECL For more information please contact your local sales support at www.onsemi.com Created on: 6/30/2016
