Highway Data Rate Selection
The highway data rate for a particular transmit or receive highway is selected by setting HDR[1—0] (bits 1—0) in
byte 2 of the highway configuration registers. All of the highways in the TTSI2K32T are grouped into pairs. RXD0 is
paired with RXD1, RXD2 is paired with RXD3, . . . , and RXD30 is paired with RXD31. Similarly, TXD0 is paired
with TXD1, TXD2 is paired with TXD3, . . . , and TXD30 is paired with TXD31.
The maximum combined bandwidth that each pair can handle is 8.192 Mbits/s. If the programmed bandwidth of a
pair exceeds 8.192 Mbits/s, one or both highways will be set to idle automatically. The register contents will not be
altered to reflect this, but that particular receive or transmit highway will not carry any traffic.
Table 6 shows the valid Rx highway data rate options for a particular Rx highway pair.
Table 6. Rx Highway Data Rate Options
* i = 0, 1, 2, . . . , 15.
Table 7 shows the valid Tx highway data rate options for a particular Tx highway pair.
Table 7. Tx Highway Data Rate Options
* i = 0, 1, 2, . . . , 15.
To meet the 8.192 Mbits/s bandwidth requirement for a transmit highway pair, a transmit highway may have to be
disabled. This is done by setting its data rate to 0.000 Mbits/s and not by setting its XE bit to 0 in the transmit con-
figuration register.
