405 lines from Raspberry Pi 5

Makes sense as it only has a UHF osc. Below 460 MHz it's the output of a /2, /4, 8 or /16 that feeds the two modulators.
A couple of LC stages with caps switched by GPIO, or varicaps fed by DAC is really needed for VHF. Significant that the VHF bands are done simply by dividing the VCO and the control bits are part of the test settings register.

Ha! The NXP datasheet is an over printed Freescale one! So much for seeing has they a better explination!
