ISOUSB111DWXR from Texas Instruments is a Low-emission isolated USB repeater supporting low and full speed - USB isolators. ISOUSB111 is a galvanically-isolated USB 2.0 compliant repeater supporting low speed (1.5Mbps) and full speed (12Mbps) signaling rates. The device supports automatic connect and speed detection, reflection of pull-ups/pull-downs, and link power management allowing drop-in USB hub, host, peripheral and cable isolation. The device also supports automatic role reversal - if after disconnect, a new connect is detected on the Upstream facing port, then the Upstream and Downstream port definitions are reversed. This feature enables the device to support USB On-The-Go (OTG) and Type-C Dual Role Port (DRP) implementations. This device uses a silicon dioxide (SiO2) insulation barrier with a withstand voltage of up to 5000VRMS and a working voltage of 1500VRMS. Used in conjunction with isolated power supplies, the device protects against high voltage, and prevents noise currents from the bus from entering the local ground. The ISOUSB111 device is available for reinforced isolation. The device supports a wide ambient temperature range of -40°C to 125°C. The device is available in the standard SOIC-16 (16-DW) package and a smaller SSOP-16 (16-DWX) package.

DS560DF810ALUT from Texas Instruments is a 56-Gbps, eight-channel retimer with 2x2 crosspoint - Ethernet retimers, redrivers & mux-buffers. The DS560DF810 is an eight-channel multi-rate retimer with integrated signal conditioning. It extends the reach and robustness of long, lossy, crosstalk-impaired high-speed serial links. Each channel in the DS560DF810 independently locks to symbol rates (PAM4 and NRZ) in a continuous range from 19.6 to 28.9 GBd or to any supported sub-rate. The integrated CDR function is an excellent choice for front-port optical module applications to reset the jitter budget and retime the high-speed serial data. These features allow for individual lane forward error correction (FEC) pass-through. In addition, the DS560DF810 supports automatic lane rate switching for CDR lock up to five different combinations of baud rates and modulation types without host intervention. The advanced equalization features of the DS560DF810 include a continuously adaptive continuous-time linear equalizer (CTLE), RX feed-forward equalizer (FFE), decision feedback equalizer (DFE), and a programmable, low-jitter 4-tap TX feed-forward equalizer (FFE) filter. These features enable reach extension for lossy interconnects such as direct-attach copper (DAC) cables and backplanes with multiple connectors and crosstalk. The DS560DF810 is equipped with a bit mux and de-mux gearbox for simple NRZ-to-PAM4 or PAM4-to-NRZ conversion between host and module. The gearbox is capable of aggregating a pair of NRZ inputs up to 28.9 GBd into one 28.9 GBd PAM4 output as well as de-aggregating a single 28.9 GBd PAM4 input into a pair of 28.9 GBd NRZ outputs. The DS560DF810 implements a full 2×2 crosspoint between each pair of adjacent channels after the CDR to enable fast and flexible lane switching for PCB routing flexibility, 2-to-1 multiplexing and 1-to-2 de-multiplexing for failover redundancy, and 1-to-2 fanout for diagnostic monitoring. In addition, integrated physical AC coupling capacitors (TX and RX) eliminate the need for external capacitors on the PCB. These features reduce PCB routing complexity and bill of material (BOM) cost. Diagnostic capabilities include a non-destructive PAM4/NRZ vertical eye height monitor, a 2D PAM4/NRZ eye opening monitor (EOM), PRBS pattern generator with error injector module, PRBS error checker, and on-die temperature sensor. These features help to gauge the margin of the link and can be used to monitor the health of the system over time. The DS560DF810 can be configured either through I 2C or through an external EEPROM. Up to 16 devices can share a single EEPROM.
