28 July 2003 Sunnyvale, CA Lightwave--Maxim Integrated Products introduces the MAX9394/MAX9395 integrated 2:1 multiplexer and 1:2 demultiplexer with loopback. The MAX9394 multiplexer accepts LVDS, HSTL, and other GND-referenced input signals. The MAX9395 demultiplexer accepts LVPECL, CML, and other Vcc-referenced differential input signals.
Three LVCMOS/LVTTL inputs activate the loopback mode, connecting both the input of first channel to the output of the second channel, and the selected input of the second channel to the outputs of the first channel. Independent, individual enable inputs control the LVDS
outputs.
The MAX9394/MAX9395 have low jitter (60 psec peak-to-peak typically) and low pulse skew (12.6 psec typically) at 1.34-GHz maximum frequency. As a result, these devices are ideal for protection switching in fault-tolerant systems, loopback switching for diagnostics, and fanout buffering for applications such as clock/data distribution in central office switches, networking switches and routers, and SONET/SDH communications.
The MAX9394/MAX9395 operate from a 3.3V ±10% supply and are specified over the extended temperature range (-40°C to +85°C). Both devices are available in 32-pin TQFP and 32-pin thin QFN packages. Refer to the MAX9394/MAX9395 data sheet for package outlines.
Prices start at $4.48 for the TQFP and $4.88 for the QFN (1000-up, FOB USA).
