The use of TJUST_REQ on the transmit SBI336 interface is dependent on whether the SBS is
configured as connecting to a physical layer device or link layer device. The interface connection
type refers to the Incoming and Outgoing SBI buses therefore the configuration of the transmit
SBI336 interface is opposite to that of the Incoming SBI336 bus. In Figure 39 TJUST_REQ is
shown as a transmit SBI336 bus output which is consistent with the SBS configured for
connection to a physical layer device, meaning that the transmit SBI336 interface is expected to
connect to a link layer type device. When the SBS is configured for connection to a link layer
device, TJUST_REQ is not used and is held low.

Receive TelecomBus Functional Timing
Figure 40 shows the receive TelecomBus functional timing. This figure is very similar to the
Incoming 77.76 MHz TelecomBus Functional Timing shown in Figure 34. The main difference is
that the timing is provided by the 77.76 MHz SYSCLK.
