Function
payload active signal identifies the payload bytes on
LADATA[7:0]. LAPL is set high during path overhead
and payload bytes and low during transport overhead
bytes.
By default, LAPL is only asserted during the
SONET/SDH tributaries assigned to this device as
determined by the LAOE bit in the TTMP Tributary
Control registers. As options, LAPL can be driven
during transport overhead, for all bytes of an STM-1
when configured for 77.76MHz operation or all the
time.
LAPL is updated on the rising edge of LREFCLK.
V5 byte signal marks the various tributary V5 bytes.
LAV5 marks each tributary V5 byte on the LADATA[7:0]
bus when high.
By default, LAV5 is only asserted during the
SONET/SDH tributaries assigned to this device as
determined by the LAOE bit in the TTMP Tributary
Control registers. As options, LAV5 can be driven
during transport overhead, for all bytes of an STM-1
when configured for 77.76MHz operation or all the
time.
LAV5 is updated on the rising edge of LREFCLK.
Line Drop Bus Data (LDDATA[7:0]). The drop bus
data contains the SONET/SDH receive payload data in
byte serial format. LDDATA[7] is the most significant
bit, corresponding to bit 1 of each serial word, the bit
transmitted first.
LDDATA[7:0] is sampled on the rising edge of
LREFCLK.
