Overview
 The Lattice Open Base Station Architecture Initiative Reference Point 3 Specification (OBSAI RP3) IP core together with SERDES and Physical Coding Sublayer (PCS) functionality integrated in the LatticeSC and LatticeECP2M series FPGAs implements the physical and data link layers of the OBSAI RP3 specification and can be used in applications connecting wireless baseband and RF modules. Control and status parameters specifying core functionality are managed via bit-mapped I/O that may be hard-wired or interfaced to programmable registers, providing users with optimal flexibility in defining static and/or dynamic management of the various functional parameters needed for their particular applications.
Features
- Supports the physical link layer of the OBSAI RP3 specification
- Supports the data link layer of the OBSAI RP3 specification
- Supports the three standard bit rates of the OBSAI RP3 specification (768 Mb/s, 1536 Mb/s, and 3072 Mb/s)
- OBSAI data link parameter values specified via separate dedicated I/O allowing hardwired configuration or register-based programmable control of core functionality. See the user guide for parameter and range details
- GUI-selectable CDMA and WCMA, GSM/EDGE, 802.16 evaluation configurations
- Top-level evaluation wrapper including source RTL for control and status management register set accessed via integrated LatticeSC System Bus and JTAG interface
New in Version 3.0 (see User Guide for details):
- Support for Transport layer multiplexing/demultiplexing
- RP3-01 Messaging support: Clock Burst, RTT Measurement, Virtual Hardware Reset
- Ethernet messaging
