SINL[0]
Input
121 The left systolic input bus (SINL[8:0]) carries
SONET/SDH frame data in byte serial format. The
SINL[8] bit is a parity bit which is not passed through

the TUDX. The TUDX may be configured to check for
even or odd input bus parity and generate interrupts
when parity errors occur. The SINL[8:0] bus is
sampled on the rising edge of SCLK. Data on the
SINL[8:0] bus is re-timed and may be routed to the
DOUTL[8:0] in place of information switched from the
DINT[8:0] bus, and is provided for constructing larger
switching arrays using systolic data flow.

The right systolic input bus (SINR[8:0]) carries
SONET/SDH frame data in byte serial format. The
SINR[8] bit is a parity bit which is not passed through
the TUDX. The TUDX may be configured to check for
even or odd input bus parity and generate interrupts
when parity errors occur. The SINR[8:0] bus is
sampled on the rising edge of SCLK. Data on the
SINR[8:0] bus is re-timed and may be routed to the
DOUTR[8:0] in place of information switched from the
DINB[8:0] bus, and is provided for constructing larger
switching arrays using systolic data flow.

SOUTT[8] bit is a parity bit which is generated by the
TUDX. The TUDX may be configured to generate
even or odd parity. The SOUTT[8:0] bus is updated on
the rising edge of SCLK. The SOUTT[8:0] bus carries
a re-timed copy of the information sampled on the
DINT[8:0] bus and is provided for constructing larger
switching arrays using systolic data flow. The SOUTT
bus can be disabled to save power when not used.
