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 dB
μ
V. This should be verified for every
channel in the band.

(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.
