TDA6500; TDA6501
5 V mixer/oscillator and synthesizer for PAL and NTSC standards
[4]
The IF output signal stays stable within the range of the fref step for a low level RF input up to 120 dBV. This should be veried for every
channel in the band.
[5]
(N + 5)
1 MHz pulling is the input level of channel N + 5, at frequency 1 MHz lower, causing FM sidebands 30 dB below the wanted
carrier.
