7.68 MHz clock signal (f
(8 kHz), DCL (1536 kHz) and BCL (768 kHz) synchronous to the received S/T frames.
In LT modes these pins are input and in LT-T mode an 1536 kHz clock synchronous to
S is output at SCLK which can be used for DCL input.
The FSC signal is used to generate the pulse lengths of the different reset sources C/I
