DS21Q58 E1 Quad Transceiver

13.
The DS21Q58 can transmit and receive the 2
15
- 1 PRBS pattern. This PRBS pattern complies with ITU-T O.151
specifications. The PRBS pattern can be unframed (in all 256 bits of the frame), framed (in all time slots except
TS0), or in any single time slot. Register CCR5 contains the control bits for configuring the transmit and receives
PRBS functions. See
Table 13-1
and
Table 13-2
for selecting the transmit and receive modes of operation. In
transmit and receive mode 1 operation, the transmit- and receive-channel monitor-select bits of registers CCR3
and CCR4 have an alternate use. When this mode is selected, these bits determine which time slot transmits
and/or receives the PRBS pattern.
SR2.0 indicates when the receiver has synchronized to the PRBS pattern. The PRBS synchronizer remains in sync
until it experiences six or more bit errors within a 64-bit span. Choosing any receive mode other than NORMAL
causes the 16-bit E-bit error counter—EBCR1 and EBCR2—to be reconfigured for counting PRBS errors.
User-definable outputs OUTA or OUTB can be configured to output a pulse for every bit error received. See
Section
20
and
Table 20-1
for details. This signal can be used with external circuitry to keep track of bit-error rates
during PRBS testing. Once synchronized, any bit errors received cause a positive-going pulse, synchronous with
RCLK.

PRBS in TSx. PRBS pattern is transmitted in a single time slot (TS). In this mode, the
transmit-channel monitor-select bits in register CCR3 are used to select a time slot in which to
transmit the PRBS pattern.
