Overview: 10.3125 Gbps Retiming DualChannel Transceiver
10.3125 Gbps Retiming Dual-Channel Transceiver
ISL37231
The ISL37231 is an advanced dual-channel, dualsimplex 10.3125 Gbps retimer. It is specifically optimized for active copper cables designed to support Thunderbolt technology, but can be used for a variety of other high-speed applications. Endowed with sophisticated functions such as media optimized (PCB or Cable) and adaptive equalization, de-emphasis, and signal retiming, this IC fortifies sensitive links that break with lesser retiming solutions. The device contains high performance mixed signal processing technology to provide a maximally robust signal integrity solution for datacenter and consumer applications. Such processing includes up to 29dB of mediaoptimized equalization, and a reset of the jitter budget via retiming. The ISL37231 provides a high level of performance while significantly trimming the power required by other active cable solutions. At less than 500mW, the operating power is the lowest in class, and a sleep mode function can be invoked to reduce the power to a miniscule 2.9mW. To facilitate ease of system integration, the ISL37231 provides advanced diagnostic capabilities in the form of loopback and high-resolution on-chip eye monitor functions, both accessed via a UART interface.
