4 / 38 page December 1990 4 Philips Semiconductors Product specification Phase-locked-loop with lock detector 74HC/HCT7046A QUICK REFERENCE DATA GND = 0 V; Tamb =25 °C; 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 ORDERING INFORMATION See “74HC/HCT/HCU/HCMOS Logic Package Information”. SYMBOL PARAMETER CONDITIONS TYPICAL UNIT HC HCT fo VCO centre frequency C1 = 40 pF; R1 = 3 k Ω; VCC = 5 V 19 19 MHz CI input capacitance (pin 5) 3.5 3.5 pF CPD power dissipation capacitance per package notes 1 and 2 24 24 pF |
