73M1866B/73M1966B Data Sheet
3.3
There are three interfaces associated with the 73M1x66B: the SPI interface, the PCM highway interface
and the line interface. This section provides the timing specification for the SPI interface and the PCM
highway interface.
3.3.1 SPI Interface
Table 10 lists the characteristics for the SPI interface.
Note1: The minimal value of this parameter is for the case where only one 73M1906B is connected to the
host. If the daisy chain mode is used, the minimum SCLK cycle time increases according to the number
of slaves in the chain.
