Product specification

74HC/HCT7046A

QUICK REFERENCE DATA

GND = 0 V; Tamb = 25 °C;

SYMBOL PARAMETER

CONDITIONS

fo

VCO centre frequency

C1 = 40 pF; R1 = 3 kΩ; VCC = 5 V

CI

input capacitance (pin 5)

CPD

power dissipation capacitance per package notes 1 and 2

Notes

1. Applies to the phase comparator section only (VCO disabled).

For power dissipation of VCO and demodulator sections see Figs 20, 21 and 22.

2. CPD is used to determine the dynamic power dissipation (PD in µW):

PD = CPD × VCC2 × fi + ∑ (CL × VCC2 × fo) where:

fi = input frequency in MHz

fo = output frequency in MHz

∑ (CL × VCC2 × fo) = sum of outputs

CL = output load capacitance in pF

VCC = supply voltage in V
