2.4.11.3 Channel Hopping
TDA 5150 offers the possibility for usage of up to 4 preconfigured RF channels, called
A, B, C, and D frequency channels. The preconfiguration assumes proper programming
PLL’s Multi-Modulus Integer Value registers A/B/C/D
PLL Fractional Division Ratio registers A/B/C/D
(0x0A:0x0C/0x0E:0x10/0x12:0x14/0x16:0x18.
used for frequency channel selection. Thus it is possible to quickly switch between RF
frequency channels, without reconfiguration (assuming channels A...D have been
preconfigured in advance).
Any frequency hop inside the band requires a new Transmit Command and100 µs idle
time for the PLL to perform the VCO Auto Calibration and to settle (achieve locked state).
For frequency hops to frequencies not more than 1 MHz apart from the frequency on
which the VCO Auto Calibration was performed, it is possible to skip the VCO Auto
Calibration and thus to reduce the PLL settling time to 20µs instead of 100µs. In this case
it is allowed to start the transmission, triggered by a rising edge on the SCK line, by
waiting for only 20 µs after the Transmit Command was completed.
The VCO Auto Calibration can be skipped by setting the bit FHBLANK
GFXOSC
There should be no more than 4 consecutive jumps without VCO Auto Calibration during
transmissions.
If bit B of the Transmit Command is set, the PA will stay active, until the time-out
condition is reached (i.e. for a duration of 65536 / f
MHz reference clock)
