10.3125 Gb/s Retiming Dual-Channel Transceiver ISL37231 Features Industrys lowest power and highest performance The ISL37231 is an advanced dual-channel, dual-simplex 10.3125Gbps active cable solution for STP and twin-axial retimer for active copper cable applications. Endowed with cables sophisticated functions, such as media optimized (PCB or Cable) and adaptive equalization, de-emphasis, and signal Supports 64b/66b encoding retiming, this IC fortifies sensitive links that break with lesser Fully retimed low jitter outputs retiming solutions. The device contains high performance mixed signal processing technology to provide a maximally Up to 16.5dB of adjustable (or adaptive) receiver-side robust signal integrity solution for datacenter and consumer equalization applications. Such processing includes up to 25dB of 9dB output de-emphasis media-optimized equalization and versatile retiming Supports independent SSC on each channel capabilities to reset link jitter budgets. On-chip microcontroller and eye monitor The ISL37231 provides this high level of performance while Multiple loopback modes significantly reducing power consumption relative to other active cable solutions. At well below 500mW, the operating Low power (<420mW) operation with 3mW sleep mode power is the lowest in class, and a sleep mode function can be Ultra-small 5mmx5mm aQFN package invoked to reduce the power to a miniscule 3mW. To facilitate ease of system integration, the ISL37231 provides Applications advanced diagnostic capabilities in the form of loopback and Thunderbolt active cables high-resolution on-chip eye monitor functions, both accessed via a UART interface. Proprietary high-speed active cable assemblies The ISL37231 is optimized to work in conjunction with the Benefits ISL80083 power management IC, however, it will also operate with appropriate discrete components (voltage regulators and Thinner gauge cable a 33Mhz crystal oscillator).
