The interface to the PEF 24902 AFE V2.1 is a 6-wire interface (see
and SDR transmit and receive data is exchanged as well as control information for the
start-up procedure by means of time division multiplexing.
On SDX transmit data, power-up/down information, range function and analog loopback
requests are transferred.
On SDR level status information is received for all line ports.
On PDM0..PDM3 the ADC output data from the AFE is transferred to the DFE-Q V2.1.
The timing of all signals is based on the 15.36 MHz master clock which is provided by
the AFE.
Figure 14
The 192 available bits (related to the 15.36 MHz clock) on SDR/SDX during a 80 kHz
period are divided into 9 time-slots. 8 time-slots are 21 bits long and are reserved for data
transmission, 1 time-slot is 24 bits long and used for synchronization purposes. The
DFE-Q V2.1 uses four of them, time-slots no. 1, 3, 5 and 7.
