6/7/2004 - Texas Instruments (TI) announced two new 4x4 non-blocking crosspoint switches that operate at more than 2.0 gigabits per second (Gbps). The devices come in a flow-through pin-out, which allows for ease in printed circuit board (PCB) layout. Low-voltage differential signaling (LVDS) outputs are used to achieve a high-speed data throughput while using low power. The devices are ideal for clock buffering and muxing or data transmission in datacom and telecom applications such as high-speed network routing and wireless base stations.
Each output driver of the SN65LVDS250 and SN65LVDT250 includes a 4:1 multiplexer to allow any input to be routed to any output. Internal signal paths are fully differential to achieve high signaling speeds while maintaining low signal skews. The SN65LVDT250 incorporates 110-ohm termination resistors for applications where board space is at a premium. The SNLVDS250 and SNLVDT250 are available in volume in a 38-pin TSSOP package from TI and its authorized distributors. Suggesting pricing in quantities of 1,000 is $7.75.
