HEF4046BT,653

Clock Generators, PLLs, Frequency Synthesizers Overview

The HEF4046BT,653 is a phase-locked loop circuit manufactured by Nexperia in the SO16 plastic small outline package (SOT109-1). It integrates a linear voltage controlled oscillator (VCO) and two distinct phase comparators with a common signal input amplifier. The device operates on a supply voltage range of 3.0 V to 15.0 V. Recommended operating conditions specify 5 V to 15 V for phase-locked loop operation. Static characteristics define HIGH-level input voltage thresholds at 3.5 V (5 V supply), 7.0 V (10 V supply), and 11.0 V (15 V supply). Dynamic characteristics indicate a maximum VCO frequency of 2.7 MHz at 15 V supply.
