NOTES:
1. The negative bias voltages specified are generated on-chip using an internal oscillator. Two external capacitors, CNB and CSUB, of
47nF are required for this purpose.
2. The characteristics are measured using an external reference resistor RCAL of value 33k wired from pins RCAL 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. CG, 4.7nF, are connected between
gate outputs and ground, CD, 10nF, are connected between drain outputs and ground.
5 . These parameters are linearly related to VCC
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.
