CONTROL INTERFACES AND REGISTER DESCRIPTIONS
REGISTER INFORMATION
A unidirectional 3-wire serial bus sets the ML2722’s transceiver parameters and programs the PLL circuits.
Programming is performed by entering 16-bit words into the ML2722 serial interface. Three 16-bit registers are
partitioned such that 14 bits are dedicated for data to program the operation and two bits identify the register address.
The three registers are:
Register 0:
PLL Configuration
Register 1:
Channel Frequency Data
Register 2:
Internal Test Access
Figure 5 shows a register map. Table 4 through Table 6 provide detailed diagrams of the register organization: Table 4
and Table 5 outline the PLL configuration and channel frequency registers, and Table 6 displays the filter tuning and test
mode register.
