Serial Interface with Time Slot Assigner
RFSDx—Receive Frame Sync Delay for TDM A or B

These two bits determine the number of clock delays between the receive sync and the
first bit of the receive frame. Even if the CRTx bit is set, these bits do not control the delay
for the transmit frame.
Refer to Figure 7-29 and Figure 7-30 for an example of the use of these bits.
Some TDMs such as GCI define the input clock to be 2 faster than the data rate. This bit
controls this option.
This bit is useful when the transmit and receive sections of a given TDM use the same
clock and sync signals. In this mode, L1TCLKx and L1TSYNCx pins can be used as gen-
eral-purpose I/O pins.
00 = No bit delay (The first bit of the frame is transmitted/received on the same clock
01 = 1-bit delay (Use for IDL.)
10 = 2-bit delay
11 = 3-bit delay
0 = The channel clock (L1RCLKx and/or L1TCLKx) is equal to the data clock. (Use for
1 = The channel clock rate is twice the data rate. (Use for GCI.)
0 = Separate pins. The receive section of this TDM uses L1RCLKx and L1RSYNCx
1 = Common pins. The receive and transmit sections of this TDM use L1RCLKx as
0 = Normal operation.
