Receive SBI336 Functional Timing
Figure 41 shows the receive TelecomBus functional timing. This figure is very similar to the
Incoming SBI336 Functional Timing shown in Figure 32. The main difference is that the timing
is provided by the 77.76 MHz SYSCLK.
The use of RJUST_REQ on the receive 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 receive
SBI336 interface is opposite to that of the Outgoing SBI336 bus. In Figure 41 RJUST_REQ is
shown as a receive SBI336 bus input which is consistent with the SBS configured for connection
to a link layer device, meaning that the receive SBI336 interface is expected to connect to a
physical layer type device. When the SBS is configured for connection to a physical layer device,
RJUST_REQ is not used.
