Gb/s Retiming Dual-Channel Transceiver ISL37231 The ISL37231 is an advanced dual-channel, dual-simplex retimer for active copper cable 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 25dB of media-optimized equalization and versatile retiming capabilities to reset link jitter budgets. The ISL37231 provides this high level of performance while significantly reducing power consumption relative to other active cable solutions. At well below 500mW, the operating power is the lowest in class, and a sleep mode function can be invoked to reduce the power to a miniscule 3mW. 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. The ISL37231 is optimized to work in conjunction with the ISL80083 power management IC, however, it will also operate with appropriate discrete components voltage regulators and a 33Mhz crystal oscillator . • Industry’s lowest power and highest performance 10.3125Gbps active cable solution for STP and twin-axial cables • Supports 64b/66b encoding • Fully retimed low jitter outputs • Up to 16.5dB of adjustable or adaptive receiver-side equalization • 9dB output de-emphasis • Supports independent SSC on each channel • On-chip microcontroller and eye monitor • Multiple loopback modes • Low power <420mW operation with 3mW sleep mode • Ultra-small 5mmx5mm aQFN package • Thunderbolt active cables • Proprietary high-speed active cable assemblies • Thinner gauge cable • Extends cable reach • Improved BER TX1 RX1 TX2 RX2 GND CABLE CONNECTOR ISL37231 AI1 EQ CDR DE BO1 DE CDR EQ BI1 AI2 EQ CDR DE AO2 BO2 DE CDR EQ BI2 ACTIVE CABLE CABLE MEDIA CABLE CONNECTOR ISL37231 BI1 EQ CDR DE BO1 AO1 DE CDR EQ AI1 BI2 EQ CDR DE BO2 AO2 DE CDR EQ AI2 RX1 TX1 RX2 TX2 GND PWR CLK RESET SDA SCL SDA RESET CLK PWR ISL80083 EEPROM EEPROM ISL80083 FIGURE TYPICAL APPLICATION January 25, 2013 FN8266.1 CAUTION These devices are sensitive to electrostatic discharge follow proper IC Handling Procedures. 1-888-INTERSIL or 1-888-468-3774 \| Copyright Intersil Americas LLC 2012, All Rights Reserved Intersil and design is a trademark owned by Intersil Corporation or one of its subsidiaries.
