Crosspoint switch

Crosspoint switch

The single-chip S2028A bipolar, 1.5-Gbit/sec 33 ¥ 32 differential crosspoint switch suits applications such as high-speed, high-bandwidth telecommunications and data-communications network switching products. The switch can be selectively reconfigured one output channel at a time in unicast mode, 16 output channels at a time in multicast mode, and all 32 output channels simultaneously in broadcast mode. Along with single-cycle reconfiguration of the entire 32 ¥ 32 crosspoint switch, the unit features single-cycle broadcast and fast two-cycle multicast configuration. The unit operates on a +5.0V supply voltage. A differential 10K pecl data path minimizes data distortion. It comes in a 224-pin ldcc package with straight leads and attached heat sink. Price is $380 in 100-piece quantities. The company also offers 1.5-Gbit/sec 16 ¥ 16 and 32 ¥ 32 differential crosspoint switches as well as an 800-Mbit/sec 32 ¥ 32 single-ended crosspoint switch.
