OBSAI RP3

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. Parameters and ranges supported include:

Number of Messages in Message Group (M_MG = 4 to 255)
Number of IDLE bytes at end of Message Group (K_MG = 1 to 19)
Index that determines line rate (RATE_INDEX = 1, 2, 4)
