IHSMODEB Input
W3
The active low incoming High-Speed interface
mode signal (IHSMODEB) configures the
incoming interface mode of the TUPP+622.
When IHSMODEB is set low, the 77.76 MHz
STM-4 (STS-12) interface mode is selected.
SCLK must be connected to GSCLK[0].
IC1J1[1], IPL[1], ITMF[1], IDP[1], ID[7:0],
ITV5[1], ITPL[1], IAIS[1] are sampled on the
rising edge of HSCLK. When IHSMODEB is set
high, the 19.44 MHz STM-1 (STS-3) interface
mode is selected. IC1J1[4:1], IPL[4:1],
ITMF[4:1], IDP[4:1], ID[31:0], ITV5[4:1],
ITPL[4:1], IAIS[4:1] are sampled on the rising
edge of SCLK. IHSMODEB has an integral pull-
up resistor.
OHSMODEB
Input
Y2
The outgoing High-Speed interface mode signal
(OHSMODEB) configures the outgoing interface
mode of the TUPP+622. When OHSMODEB is
set low, the 77.76 MHz STM-4 (STS-12)
interface mode is selected. SCLK must be
connected to GSCLK[0]. OTMF[1] and
GSCLK_FP are sampled on the rising edge of
HSCLK. ODP[1], OTPL[1], OTV5[1], OD[7:0],
AIS[1], IDLE[1], OC1J1V1[1] and OPL[1] are
updated on the rising edge of HSCLK. When
OHSMODEB is set high, the 19.44 MHz STM-1
(STS-3) interface mode is selected. OTMF[4:1]
are sampled on the rising edge of SCLK.
ODP[4:1], OTPL[4:1], OTV5[4:1], OD[31:0],
AIS[4:1], IDLE[4:1], OC1J1V1[4:1] and OPL[4:1]
are updated on the rising edge of SCLK.
OHSMODEB has an integral pull-up resistor.
