Description/Nominal Signal Levels
The SPI LATCH U11 is used to configure the WIB by means of several MUXs and Analog switches.
The output pins 1 to 6 and pin 15 drive the select inputs of the
configuration path switches and amplification step switches.
On the TTN 5068A (8-Wire) a second SPI Latch (U15) is used
to configure the two additional paths in the same manner as above.
The continuous Master Clock and the Bit Clock are essential for the correct data transfer and data
sampling.
Both are square waves with the duty cycle 1:1 with a period of 3,9 µsec.
The continuous Frame Sync Clock starts the PCM serial Block Transfer
The waveform is a needle pulse train with a repetition rate of 125 µsec.
The Jumper fields P1, P5, P8 and P9 have to have in any case jumpers set.
When running the board without any jumpers the correct function cannot be guaranteed.
(undefined matching). The default jumper setting is for 600 Ohms (Position A)
