TDA6500; TDA6501
5 V mixer/oscillator and synthesizer for PAL and NTSC standards
The module address contains programmable address bits (MA1 and MA0) which offer the
possibility of having up to 4 synthesizers in one system by applying a specific voltage on
the AS input.
Table 7
gives the relationship between the input voltage applied to the AS
input and bits MA1 and MA0.
[1]
The ADC input cannot be used when these test modes are active; see
Section 7.2.2
for more information.
[1]
The AGC detector is disabled. Both the sinking and sourcing currents from the IC are disabled. The AGC
output goes into a high-impedance state and an external AGC source can be connected in parallel.
[2]
The AGC detector is disabled and the fast mode current source is enabled.
