Transceivers Target Next-Generation Networks

Eyeing the next generation of networking system designs, the HRP2100 parallel-data and the SRP3100 serial-data transceivers incorporate core technologies that are claimed to meet the emerging demand for systems supporting interconnect data rates of 10 Gb/s and greater. The HRP2100 provides 16-Gb/s, full-duplex data transmission for an aggregate raw bandwidth of 32 Gb/s. Power dissipation is less than 600 mW and the device can tolerate up to 1.2 ns of skew. Other features include on-chip timing calibration and low-voltage differential signaling. The IC comes in a 292-pin PBGA package and is intended for twisted-pair, coaxial and optical interconnect applications at distances up to 30m. The SRP3100 is available in two versions: one supports 2.5-Gb/s data rates from a 125-MHz reference clock and the other supports 3.125-Gb/s rate from a 156-MHz clock. The chip supports Fibre Channel, Infiniband and Gbit Ethernet standards. Four of these devices can be bundled to achieve point-to-point, 10-Gb Ethernet connectivity. The IC comes in an 80-pin TQFP and operates with a 2.5V core power supply and 3.3V TTL interface. Pricing for the HRP2100 is $129 and the SRP3100 costs $37 for the 3.125-Gb/s version and $34 for the 2.5 Gb/s version, all each/1000.
