Mixed-Highway Data Rates
Each receive (Rx) highway can be selected to sample at a rate of either 2.048 Mbits/s, 4.096 Mbits/s, or
8.192 Mbits/s. This rate selection is made via the HDR[1—0] field in the receive highways configuration register
(byte 2). Similarly, each transmit (Tx) highway can be programmed to clock the data out at 2.048 Mbits/s,
4.096 Mbits/s, or 8.192 Mbits/s via the transmit highway configuration register (byte 2). Thus, 32 independent data
rate selections can be made: 16 on the Rx side and 16 on the Tx side. Highways can also be selected to be idle,
i.e., neither receiving nor transmitting data.
The data rate on a receive highway does not have to match that on its corresponding transmit highway either, e.g.,
RXD0 and TXD0 data rates can be different. Data received on a 2.048 Mbits/s highway can be transmitted on a
4.096 Mbits/s or 8.192 Mbits/s highway too. All of this flexibility allows this device to be used to solve a variety of
design problems such as data rate adaptation, etc. Many slow-speed highways can also be combined and sent out
on a single high-speed highway.
The figure below depicts an example where time slots are being received on different highways at different data
rates and are being switched and sent out at a slower, same, or faster data rate. Each rectangle, labeled A—N,
represents an 8-bit time slot.
