NOTES:
1. The negative bias voltages specified are generated on-chip using an internal oscillator. Two external capacitors, C
NB
and C
SUB
, of
47nF are required for this purpose.
2. The characteristics are measured using an external reference resistor R
CAL
of value 33k wired from pins R
CAL
to ground.
3. Noise voltage is not measured in production.
4. Noise voltage measurement is made with FETs and gate and drain capacitors in place on all outputs. C
G
, 4.7nF, are connected between
gate outputs and ground, C D , 10nF, are connected between drain outputs and ground.
5 . These parameters are linearly related to V CC
6. These parameters are measured using Test Circuit 1
7. These parameters are measured using Test Circuit 2
8. The ZNBG32 series will also reject DiSEqC
 and other common switching bursts.
