CMOS Transceivers

HotRail, Inc.. has introduced two high-bandwidth CMOS transceivers for networking applications. The new ICs are the HotRail Channel HRP2100 parallel data transceiver, supporting up to 16 gigabits per second (Gbps) chip-to-chip transmission rates, and the SkyRail Link SRP3100 serial transceiver, which supports either 2.5 Gbps or 3.125 Gbps data rate interconnect applications at distances up to 30 meters.

The new HotRail Channel HRP2100 IC provides 16 Gbps, full-duplex data transmission (for an aggregate raw bandwidth of 32 Gbps), with a power dissipation of less than 600 mW. Optimized for efficient, low Bit Error Rate data transmission, the IC contains on-chip timing calibration circuitry and uses low-voltage differential signaling to reduce noise and error probability.

As a board-level interconnect, the HRP2100 supports one-meter maximum trace lengths. It tolerates up to 1.2 ns of data skew. Produced in a 0.25-micron, 4-layer metal process, the IC comes in a 292-pin PBGA, compared to similar data rate ICs requiring packages with more than 1000 pins.

The SkyRail Link SRP3100 is a serial transceiver for high-performance twisted-pair, coaxial and optical interconnect applications at distances up to 30 meters. The SRP3100 is available in two speed grades, supporting data rates of 2.5 Gbps from a 125 MHz reference clock and 3.125 Gbps from a 156 MHz clock. The IC supports Fibre Channel, Infiniband and Gigabit Ethernet standards. Four SkyRail Link ICs can be bundled to achieve point-to-point, 10 Gb Ethernet connectivity. Power dissipation for each IC is a low 500 mW. Manufactured in a 0.25-micron CMOS process, the chip is packaged in an 80-pin TQFP and operates with a 2.5 V core power supply and 3.3 V TTL interface.
