IN74HC4046A
TECHNICAL DATA
Phase-Locked Loop
High-Performance Silicon-Gate CMOS
The device inputs are patible with standard CMOS outputs; with pullup resistors, they are patible with LS/ALSTTL outputs. The IN74HC4046A phase-locked loop contains three phase parators, a voltage-controlled oscillator (VCO) and unity gain opamp DEMOUT. The parators have two mon signal inputs, PIN, and SIGIN. Input SIGIN and PIN can be used directly coupled to large voltage signals, or indirectly coupled (with a series capacitor to small voltage signals). The self-bias circuit adjusts small voltage signals in the linear region of the amplifier. Phase parator 1 (an exclusive OR gate) provides a digital error signal PC1OUT and maintains 90 degrees phase shift at the center frequency between SIGIN and PIN signals (both at 50% duty cycle). Phase parator 2 (with ORDERING INFORMATION leading-edge sensing logic) provides digital error signals PC2OUT and IN74HC4046AN Plastic PCPOUT and maintains a 0 degree...
