IGAD2DY11A is an LP (Low Power) Die-to-Die (D2D) PHY for SoIC-X Face-to-Face advanced package. This GUCIe PHY not only supports UCIe specification rev 1.1 compliance physical layer and Raw D2D interface (RDI) but also optionally provides the GUC proprietary Physical Coding Sublayer (PCS) to provide low- latency flow control for fast linked with AXI/CXS bus and provide error data replay (PCS-replay) feature to ensure the data transferred to RX is error-free. This IP is the UCIe Advanced package compliant that transmits data through TSMC advanced packaging solution at Chip-on-Wafer-on-Substrate (CoWoS® ) with the Silicon and Redistribution Layer (RDL) interconnect interposer.
IGAD2DY11A contains 64 TX lanes and 64 RX lanes per module and supports the configurable number of modules up to eight in one PHY. Each TX/RX lane supports up to a 4/8/12/16/24/32/36 GT/s data rate. In summary, This IP offers a full-duplex data transmission with extremely low power and up to 2304 GT/s data rate per module in both directions. IGAD2DY11A contains the Electrical (Analog) Layer and Logical PHY Layer that support
serialization, deserialization, link training, eye training, lane repair, lane reversal, scrambling and descrambling, sideband initialization and transfer, and clock forwarding functions. A Phase-Locked Loop (PLL) is also included.
