Product Overview
For connector-facing ports, the receiver equalization mode can be adaptive or fixed. For system-facing ports, the SSRX1/2 transmitters support linear or limited redriver operation. Power modes include 550 mW typical active power, 1.5 mW disconnect power, and 0.130 mW disabled power when EN is low.
The device uses a single 3.3 V supply, with recommended VCC limits of 3.0 V minimum, 3.3 V nominal, and 3.6 V maximum. VCC ramp time is specified from 0.1 ms to 50 ms, and VCC noise is limited to 50 mVpp below 4 MHz. The RNQ WQFN 40-pin, 6 mm x 4 mm package has specified thermal metrics including 31.4 °C/W junction-to-ambient resistance and 4.3 °C/W junction-to-case bottom resistance.
