The DS50PCI402 is a low power, 4 lane bidirectional buffer/equalizer designed specifically for PCI Express Gen1 and Gen2 applications. The device performs both receive equalization and transmit de-emphasis, allowing maximum flexibility of physical placement within a system. The receiver is capable of opening an input eye that is completely closed due to inter-symbol interference (ISI) induced by the interconnect medium. The transmitter de-emphasis level can be set by the user depending on the distance from the DS50PCI402 to the PCI Express endpoint. The DS50PCI402 contains PCI Express specific functions such as Transmit Idle, RX Detection, and Beacon signal pass through. The device provides automatic receive detection circuitry which controls the input termination impedance. By automatically reflecting the current load impedance seen on the outputs back to the corresponding inputs the DS50PCI402 becomes completely transparent to both the PCIe root complex and endpoint. An internal rate detection circuit is included to detect if an incoming data stream is at Gen2 data rates, and adjusts the de-emphasis on it's output accordingly. The signal conditioning provided by the device allows systems to upgrade from Gen1 data rates to Gen2 without reducing their physical reach. This is true for FR4 applications such as backplanes, as well as cable interconnect.

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. The DS560DF810 is an eight-channel multi-rate retimer with integrated signal conditioning.

The DS560MB410 is a low-power, high-performance four-channel linear equalizer supporting multi-rate, multi-protocol interfaces up to 28 GBd using four-level pulse amplitude modulation (PAM4), or up to 32 GBd using non-return-to-zero (NRZ) modulation. It is used to extend the reach and robustness of high-speed serial links for backplane, midplane, and active copper cable (ACC) applications. The DS560MB410 can increase the reach between two ASICs by 18+ dB beyond the normal ASIC-to-ASIC reach. Each channel operates independently with a user-selectable CTLE boost profile optimized for equalizing either PCB or copper cable loss profiles. The linear nature of the DS560MB410’s equalization preserves input signal characteristics traveling through the redriver. This transparency allows link partner ASICs to negotiate Tx equalizer coefficients freely during link training and to support individual lane Forward Error Correction (FEC) pass-through in mission mode with minimal effect on latency. The DS560MB410 includes a full 2×2 crosspoint between each pair of adjacent channels to enable 2-to-1 multiplexing and 1-to-2 de-multiplexing for failover redundancy, 1-to-2 fanout for diagnostic monitoring, and signal crossover (NRZ only up to 32 GBd) for PCB routing flexibility. The crosspoint is controllable through pins or the SMBus register interface. The DS560MB410’s small package dimensions and optimized high-speed signal escape are an excellent choice for small form-factor applications.
