Advance Information
MT91L62
7-177
Dout, on the rising edge of BCL during the time slot
defined by the STB input. Dout is tri-stated at all
times when STB is not true. If STB is valid, then quiet
code will be transmitted on Dout during the valid
strobe period. There is no frame delay through the
PCM serial circuit for synchronous operation.
For asynchronous operation Dout and Din are as
defined for synchronous operation except that the
allowed output jitter on Dout is larger. This is due to
the resynchronization circuitry activity and will not
affect operation since the bit cell period at 128 kb/s
and 256 kb/s is relatively large. There is a one frame
delay
through
the
PCM
asynchronous operation. Refer to the specifications
of Figures 5 & 6 for both synchronous and
asynchronous SSI timing.

While the MT91L62 is held in PWRST no device
control or functionality is possible.
