The outgoing byte interface mode signal
(OBMODE) configures the outgoing interface
mode of the TUPP-PLUS. When OBMODE is
set low, nibble interface mode is selected. SCLK
must be connected to GSCLK[0]. OTMF, OC1J1
and OPL are sampled on the rising edge of
NSCLK. ODP, OTPL, OTV5, OD[3:0], AIS, IDLE,
LC1J1V1, LPL, and LOM[3:1] are updated on
the rising edge of NSCLK. When OBMODE is
set high, byte interface mode is selected. OTMF,
OC1J1 and OPL are sampled on the rising edge
of SCLK. ODP, OTPL, OTV5, OD[7:0], AIS,
IDLE, LC1J1V1, LPL, and LOM[3:1] are updated
on the rising edge of SCLK. OBMODE has an
integral pull-up resister.
GSCLK[1] Output 65
GSCLK[0] 149
The generated system clock (GSCLK[1:0])
signals provide timing for the TUPP-PLUS when
nibble mode is selected at the incoming or
outgoing interface (IBMODE or OBMODE set
low). GSCLK[1:0] are a divide by two of NSCLK.
GSCLK[0] must only be connected to SCLK
externally when IBMODE or OBMODE is set
low. GSCLK[1] is a exact replica of GSCLK[0]
and can be used to supply timing to external
devices that are operating in byte mode.
GSCLK[1:0] are updated on the rising edge of
NSCLK.
