DUAL, 2 x 2 CROSSPOINT SWITCHES WITH "ANYTHING"-TO-LVDS GUARANTEE 1.50GHz MAXIMUM OPERATING FREQUENCY
SUNNYVALE, CA-May 2, 2003-Maxim Integrated Products
(NASDAQ: MXIM) introduces the MAX9390/MAX9391 dual, high-performance 2 x 2 LVDS crosspoint switches. The MAX9390 accepts LVDS, HSTL, and other GND-referenced input signals, while the MAX9391 accepts LVPECL, CML, and other VCC-referenced differential input signals.
Each channel is independently programmed to any input or both outputs, allowing each channel to be configured as a 1:2 splitter, a 2:1 multiplexer, dual repeater, or a 2 x 2 crosspoint switch. The LVDS outputs compatible with the ANSI TIA/EIA-644 LVDS standard. Low random jitter performance (2.0psRMS max), low typical output-to-output skew (10ps), and guaranteed maximum fMAX of 1.50GHz make these devices ideal for protection switching in fault-tolerant systems, loopback switching for diagnostics, and fanout buffering for clock/data distribution. Applications include central office switches, networking switches and routers, and SONET/SDH communication equipment.
The MAX9390/MAX9391 operate from 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 QFN packages. Refer to the MAX9390/MAX9391 data sheet for package outlines.
Prices start at $4.48 and $4.88 in the TQFP and QFN packages, respectively (1000-up, FOB USA).
