TDA837x family
Notes
1. On set AGC.
2. This parameter is not tested during production and is just given as application information for the designer of the
television receiver.
3. Loop bandwidth BL = 60 kHz (natural frequency fn = 15 kHz; damping factor d = 2; calculated with sync level as FPLL
input signal level). LC-VCO circuit: Q0 ≥ 60, Cext = 12 pF, Cint =20pF.
4. This parameter is not tested during production but is guaranteed by the design and qualified by means of matrix
batches which are made in the pilot production period.
5. Measured at 10 mV (RMS) top sync input signal.
6. So called projected zero point, i.e. with switched demodulator.
