3-band mixer/oscillator and PLL for
terrestrial tuners
TDA6508; TDA6508A;
TDA6509; TDA6509A
loop filter between pin CP and pin VTUNE as shown in
Fig.27. The tuning amplifier can supply up to 33 V (max.)
at pin VT for controlling any of the internal oscillators via
external tank circuits. The phase comparator can operate
at 62.5, 50 or 31.25 kHz with a 4 MHz crystal, depending
on the reference divider ratio of either 64, 80 or 128; see
Table 4. An externally sourced signal having a frequency
between 3.58 MHz and 4.43 MHz can be used as a
referencefrequencyfortheinternalcrystaloscillatoratany
of the reference divider ratios.
In test mode, port P3 will output either half the crystal
reference frequency (

) or half the reference divider
frequency (

); see Table 5.
The device can be controlled according to the I

C-bus
format; see Table 1. The in-lock flag bit FL is set to logic 1
when the PLL is locked. This flag is read from the status
byte on pin SDA during a READ operation; see Table 6
and Table 7.
Automatic frequency control is provided using an internal
Analog-to-Digital Converter controlled by the voltage on
pin ADC. The ADC code is read during a READ operation;
see Table 8.
The device requires to be addressed by five sequential
serial bytes (including the address byte) via the I
2
C-bus to
set the crystal oscillator frequency, program the five ports
and to set the charge-pump current; see Table 1. The
address byte can have one of four possible device
addresses which are selected by applying a specific
voltage to pin AS; see Table 3.
