TDA6650TT Datasheet, PDF (40/54 Pages) NXP Semiconductors – 5 V mixer/oscillator and low noise PLL synthesizer for hybrid terrestrial tuner (digital and analog)

NXP Semiconductors
TDA6650TT; TDA6651TT
5 V mixer/oscillator and low noise PLL synthesizer
The delivered current can be simply calculated with the following formula:
I_delivered
=


V_{-----D---R-C----p-}–_-u---V_{----T--}
>
I_CP
(1)
where:
I_delivered is the delivered current.
V_DC is the supply source voltage or DC-to-DC converter output voltage.
V_T is the tuning voltage.
R_pu is the pull-up resistor between the DC supply source (or the DC-to-DC converter
output) and the tuning line (R19 in Figure 27 to 30).
I_CP is the charge pump current in use.
