SP56-SM31LR10x
The Product Requirements Definition (PRD) is present to the critical design specification for SPV's SFP56 53G BASE LR transceiver. SFP56 transceiver design for single electrical lane with 53Gbps high speed data rate transmission. The integrated transmitter (TOSA) built by EML chip modulated with 26.5625Gbaud/s PAM4 signal, receiver embedded with linear transimpedance amplifier for PAM4 signal recover. Both transmitter and receiver need PAM4 retimer PAM4 CDR chip for better transmission performance. On board MCU handling all hardware and firmware initialization and boot loader, firmware design compliance with SFP+ module Management Interface SFF-8472.
