Data Sheet

Zarlink Semiconductor Inc.
4.2.1
BORS Set LOW, Non-32Mb/s Mode.
The data (channel control bit) transmitted by
BCSTo0-3
replicates the Backplane Output Enable Bit (
) of the
Backplane Connection Memory, with a LOW state indicating the channel to be set to High Impedance. Section 12.4,
Backplane Connection Memory Bit Definition, refers.
The
BCSTo0-3
outputs transmit serial data (channel control bits) at 16.384Mb/s, with each bit representing the per-
channel high impedance state for specific streams. Eight output streams are allocated to each control line as follows:
(See also
Pin Description
)
BCSTo0 outputs the channel control bits for streams BSTo0, 4, 8, 12, 16, 20, 24 and 28.
BCSTo1 outputs the channel control bits for streams BSTo1, 5, 9, 13, 17, 21, 25 and 29.
BCSTo2 outputs the channel control bits for streams BSTo2, 6, 10, 14, 18, 22, 26 and 30.
BCSTo3 outputs the channel control bits for streams BSTo3, 7, 11, 15, 19, 23, 27 and 31.
The Channel Control Bit location, within a frame period, for each channel of the Backplane output streams is
presented in
Table 3, BCSTo Allocation of Channel Control Bits to the Output Streams (Non-32Mb/s Mode)
.
As an aid to the description, the channel control bit for a single channel on specific streams is presented, with
reference to Table 3:
(1) The Channel Control Bit corresponding to Stream 0, Channel 0,
BSTo0_Ch0,
is transmitted on
BCSTo0
and is
advanced, relative to the Frame Boundary, by 10 periods of
C16o
.
(2) The Channel Control Bit corresponding to Stream 28, Channel 0,
BSTo28_Ch0,
is transmitted on
BCSTo0
in
advance of the Frame Boundary by three periods of output clock,
C16o
. Similarly, the Channel Control Bits for
BSTo29_Ch0
,
BSTo30_Ch0
and
BSTo31_Ch0
are advanced relative to the Frame Boundary by three periods of
C16o
, on
BCSTo1
,
BCSTo2
and
BCSTo3
, respectively.
The
BCSTo0-3
outputs data at a constant data-rate of 16.384Mb/s, independent of the data-rate selected for the
individual output streams,
BSTo0-31
. Streams at data-rates lower than 16.384Mb/s will have the value of the
respective channel control bit repeated for the duration of the channel. The bit will be repeated twice for 8.192Mb/s
streams, four times for 4.096Mb/s streams and eight times for 2.048Mb/s streams. The channel control bit is not
repeated for 16.384Mb/s streams.
Examples are presented, with reference to Table 3:
(3) With stream
BSTo4
selected to operate at a data-rate of 2.048Mb/s, the value of the Channel Control
Bit for
Channel 0
will be transmitted during the
C16o
clock period nos. 2040, 2048, 8, 16, 24, 32, 40 and
48.
(4) With stream
BSTo8
operated at a data-rate of 8.192Mb/s, the value of the Channel Control Bit for
Channel 1
will be transmitted during the
C16o
clock period nos. 9 and 17.
