10.1 Gain distribution
11.1 I
The internal loop controls a fully integrated VCO, to cover the range from 950 MHz to
2175 MHz. This VCO provides both in phase and quadrature signals to drive the two
mixers.
The output of the 15-bit programmable divider passes through the phase comparator
where it is compared in both phase and frequency to the comparison frequency (f
This f
the reference divider. The buffered signal on pin XTOUT is able to drive the crystal
frequency input of the SDD, which saves a crystal in the application.
The output of the phase comparator drives the charge pump and loop amplifier section.
Pin CP is the output of the charge pump, and pin VT drives the tuning voltage to the
varicap diode of the voltage controlled oscillator. The loop filter has to be connected
between pins CP and VT.
For test and alignment purposes, it is possible to release the tuning voltage output and to
apply an external voltage on the VT pin, as well as to select the charge pump sink, source
or off.
The programming of the TDA8263HN is done through the I
selection is done through the R/W bit (address LSB). The TDA8263HN fulfils the fast
mode I
9398 393 40011.

3.3 V or 5.0 V, which allows direct connection to most of existing microcontrollers.
Data transfer format should be MSB first, and 8-bit word + acknowledge bit.
