The NT-Mode is supported together with the Quad IEC DFE-Q V2.1. In this application
the serial interface SDX does only carry control information. The transmit data is
transferred from the Quad IEC DFE-Q V2.1 to the Quad IEC AFE asynchronously on all
four ports via the pins XDN1..4. The PLL of the Quad IEC AFE is used to synchronize the
crystal frequency onto the received signal of the U-interfaces. Operation of all four ports
is synchronized individually onto the receive signal from the line by a digital PLL in the
Quad IEC DFE-Q.
