MAX14986ETI+

Signal Buffers, Repeaters, Splitters Overview

The MAX14986ETI+ is a dual-channel redriver designed for SAS and SATA signals up to 6.0GT/s, operating from a single +3.3V supply. It features independent input equalization and output preemphasis to enhance signal integrity. The device includes internally 50Ω terminated inputs and outputs requiring AC coupling. Electrical characteristics specify an operating power-supply range of 3.0V to 3.6V, with typical supply currents ranging from 140mA to 220mA depending on configuration. Standby current is typically 16mA. Input and output return loss is specified at -7.9dB up to 3.0GHz. Deterministic jitter is 23psP-P maximum, and random jitter is 1.5psRMS maximum at 6.0GT/s.
