INTERFACING
The ADF4116 family has a simple SPI-compatible serial inter-
face for writing to the device. SCLK, SDATA and LE control
the data transfer. When LE (Latch Enable) goes high, the 24 bits
which have been clocked into the input register on each rising
edge of SCLK will get transferred to the appropriate latch. See
Figure 1 for the Timing Diagram and Table II for the Latch
Truth Table.

Figure 28. Direct Conversion Transmitter Solution
The maximum allowable serial clock rate is 20 MHz. This means
that the maximum update rate possible for the device is 833 kHz or
one update every 1.2 microseconds. This is certainly more than
adequate for systems which will have typical lock times in hun-
dreds of microseconds.
