5 V mixer/oscillator and synthesizer for PAL and NTSC standards
[4] The IF output signal stays stable within the range of the f_ref step for a low level RF input up to 120 dBµV. This should be verified 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.
