The receive data signals (RD[31:0]) contain

the recovered line data for the 32

independently timed links in normal mode

(PMCTEST set low). Processing of the

receive links is on a priority basis, in

descending order form RD[0] to RD[31].

Therefore, the highest rate link should be

connected to RD[0] and the lowest to

RD[31].

For channelised links, RD[n] contains the 24

(T1) or 31 (E1) time-slots that comprise the

channelised link. RCLK[n] must be gapped

during the T1 framing bit position or the E1

frame alignment signal (time-slot 0). The

FREEDM-32P32 uses the location of the

gap to determine the channel alignment on

RD[n].

For unchannelised links, RD[n] contains the

HDLC packet data. For certain transmission

formats, RD[n] may contain place holder bits

or time-slots. RCLK[n] must be externally

gapped during the place holder positions in

the RD[n] stream. The FREEDM-32P32

supports a maximum data rate of 10 Mbit/s

on an individual RD[31:3] link and a

maximum data rate of 52 Mbit/s on RD[2:0].

RD[31:0] is sampled on the rising edge of

the corresponding RCLK[31:0] clock.

Tristate

Output

The receive BERT data signal (RBD)

contains the receive bit error rate test data.

RBD reports the data on the selected one of

the receive data signals (RD[31:0]) and is

updated on the falling edge of RBCLK.

RBD may be tri-stated by setting the RBEN

bit in the FREEDM-32P32 Master BERT

Control register low.
