Programming
A three line bus is used to program the circuit; the
three lines being: Data IXO, Clock and Load. Data
IXO is bi-directional and is used to transmit data,
receive data and to program the circuit. The 3-line
serial bus interface allows control over the frequency
dividers and the selective powering up of Tx, Rx and
Synthesiser circuit blocks.
The interface consists of a 59-bit programming register.
Data is entered on the Data IXO line with the most
significant bit first. The first bit entered is p1, the last one
p59. The bits in the programming register are arranged as
shown in table 5.

When FSK modulation is applied to the VCO or to
the crystal oscillator the PLL is using the dividers N0
and M0. When Mod1 = 0 and Mod0 = 1 it is possible
to switch between the different dividers in the PLL.
The switching is controlled by Data IXO. When Data
IXO = 0 the PLL uses dividers N0 and M0. When Dat
IXO = 1 the PLL uses dividers N1 and M1. Switching
between the different dividers can be used to implement
low bitrate FSK modulation.

= 433.92MHz, frequency deviation: ±40kHz, f

= 10.00MHz ( Modulation is applied to the VCO.)
