The CML input and output stages are matched to the common-mode levels of SAS/SATA transceivers, so the part slots directly between the controller and the connector without external level translation. On-chip equalization on the receive side and de-emphasis on the transmit side extend the reach across lossy PCB traces, backplanes, and cable assemblies. This matters when the trace from the storage controller to the SAS/SATA connector runs more than a few inches on a standard FR-4 board — without conditioning, the eye closes before the signal reaches the drive. ## Supply, power, and package planning The 50 mA supply current per device keeps the thermal budget low on a dense line card — two lanes of redrive for roughly 165 mW at 3.3 V. The 10 pF input capacitance loads the upstream driver; verify that the controller's output driver can sink the AC terminations for the trace impedance without excessive jitter. ## Temperature grade and deployment environment The 230 ps typical propagation delay is short enough that it does not add a full bit-time of latency at 6 Gbps; budget it into the total round-trip timing for the link.","metaTitle":"DS64BR111SQE/NOPB SAS/SATA ReDriver, 6.4 Gbps, 2-Ch, Active","metaDescription":"DS64BR111SQE/NOPB dual-channel SAS/SATA redriver, 6.4 Gbps max, CML I/O with equalization and de-emphasis.
