Clock distribution devices for memory module
3 October 2007
DSP, Micros & Memory
ON Semiconductor has expanded its high performance ECLinPS clock management portfolio with the introduction of two new clock distribution devices for synchronisation of memory modules found in today's most advanced computing, data storage and networking consumer applications. The new NB4N121K and NB4N111K feature differential host clock signalling level (HCSL) outputs and ultra low propagation delay variation for fully buffered dual inline memory module (FBDIMM) applications.
The NB4N121K and NB4N111K are 3,3 V devices targeted at typical FBDIMM frequencies of 100 MHz, 133 MHz, 166 MHz, 200 MHz, 266 MHz, 333 MHz and 400 MHz. They produce additive phase jitter of only 0,3 ps and output-to-output skew <100 ps.
The NB4N121K is a 1:21 or 1:42 HCSL clock distribution device. At 1:21, the device provides a very wide fanout, and can be configured in 2X mode to provide a 1:42 HCSL fanout. It accepts differential LVPECL, CML or LVDS levels, as well as single-ended LVPECL, CML, LVCMOS or LVTTL with the proper VREFAC supply. Output drive current at the IREF pin for 1X load is selected by connecting to GND, while configuring to 2X mode is easily accomplished by connecting IREF to VCC.
The NB4N111K is a 1:10 HCSL clock distribution device. It also accepts differential LVPECL, CML or LVDS input levels, as well as single-ended LVPECL, CML, LVCMOS, or LVTTL by properly setting the VREFAC supply.
