LATTICE RELEASES REFERENCE DESIGN FOR GPON BURST MODE RECEIVER
Lattice Semiconductor Corporation announced the availability of its PURESPEED™ I/O Burst Mode Receiver (BMR) FPGA Reference Design for Gigabit Passive Optical Networks (GPON). This reference design uses Lattice's unique Adaptive Input Logic (AIL) block found on its LatticeSC™ FPGAs and LatticeSCM™ FPGAs (collectively, the LatticeSC/M family) to rapidly establish stable clock to data timing relationships within the fast lock times specified in the GPON ITU-T G.984.1 specification, which requires the Optical Line Termination (OLT) to lock to incoming data within 50 bit times.

Multiple Boundary Scan Port Addressable Buffer
The LSC BSCAN-1 is a multiple boundary scan test access port (TAP) addressable buffer function that can be accessed through a standard IEEE 1149.1 interface. With three Local Scan Ports (LSP), the BSCAN-1 function can be structured as hierarchical ports with the ability to add and remove local scan chains to improve test throughput.

Multiple Boundary Scan Port Linker
According to the IEEE 1149.1 Boundary Scan System, every complex system can have more than one boundary-scan-compliant scan port. If each of these scan ports are linked together, then the chances of enhancing the scan capability would definitely increase. In this design, the multiple scan ports are linked together by implementing instructions feed in to the IEEE 1149.1 port.
