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.
