Function
Receive Working Serial Data. In SBI336 mode, the differential
receive working serial data link (RPWRK/RNWRK) carries the
receive 77.76 MHz SBI336 data from an upstream working source,
in bit serial format, SBI336S.
In TelecomBus mode, RPWRK/RNWRK carries the receive 77.76
MHz TelecomBus from an upstream working source, in bit serial
format.
Data on RPWRK/RNWRK is encoded in an 8B/10B format
extended from IEEE Std. 802.3. The 8B/10B character bit ‘a’ is
transmitted first and the bit ‘j’ is transmitted last.
RPWRK/RNWRK are nominally 777.6 Mbit/s data streams.
Receive Protect Serial Data. In SBI336 mode, the differential
receive protect serial data link (RPPROT/RNPROT) carries the
receive 77.76 MHz SBI336 data from an upstream protect source,
in bit serial format, SBI336S.
In TelecomBus mode, RPPROT/RNPROT carries the receive
77.76 MHz TelecomBus from an upstream protection source, in bit
serial format.
Data on RPPROT/RNPROT is encoded in an 8B/10B format
extended from IEEE Std. 802.3. The 8B/10B character bit ‘a’ is
transmitted first and the bit ‘j’ is transmitted last.
RPPROT/RNPROT are nominally 777.6 Mbit/s data streams.
Receive Serial Frame Pulse. The receive serial SBI336S frame
pulse signal (RC1FP) provides system timing of the receive serial
interface.
When using the receive serial interface, RC1FP is set high once
every multiframe (4 frames for SBI without CAS, 48 frames for SBI
with CAS, and 4 frames for TelecomBus), or multiple thereof. The
RC1FP_DLY[13:0] bits (register 007H) are used to align the C1
frame boundary 8B/10B character on the receive serial interface
(RPWRK/RNWRK and RPPROT/RNPROT) with RC1FP.
RC1FP is sampled on the rising edge of SYSCLK.
