MOTOROLA
In the previous example, Motorola’s MC14LC5480 CODECs and MC145574 S/T
transceiver are shown. The S/T transceiver in this example is connected to port 0 and the
FSC0 frame sync signal is used exclusively for synchronizing the data on the transceiver’s
IDL interface. CODECs 1 and 2 are connected to frame sync 1, FSC1. CODECs 3 and 4
are connected to DFSC2 which is the output of programmable delay 2. Programmable
delay 2 generates a delayed frame sync with reference to FSC1. Similarly CODECs 5 and
6 are connected to DFSC3 which is the output of programmable delay 3. Programmable
delay 3 generates a delayed frame sync also with reference to FSC1. The MC14LC5480
CODECs, when in IDL mode, may be programmed using the FSR pin, to select whether
