Description
Inter-repeater data
. Transfers 5-bit symbol data between
NWK954s on the local expansion bus, and to/from the
backplane drivers. Transfers are synchronous to BPCLK.Require
external pull-ups for correct operation.
Local activity output
. Indicates receive activity in this
NWK954. Connects to all other NWK954s on the local
expansion bus. Output changes asynchronously.
Local activity inputs
. One input from each NWK954 on
the local expansion bus to indicate receive activity. Unused
inputs must be pulled high or connected directly to
DIGVDD. Inputs are sampled on on the rising edge of TXCLKIN.
Backplane activity output.
Indicates receive activity on
any of the NWK954s on the local expansion bus. Drives
the backplane through an external driver. Only one of the
local NWK954s is required to drive this signal, the others
should be left unconnected. Output changes asynchronously.
