NJM567D

NJM567 TONE DECODER / PHASE LOCKED LOOP ■ GENERAL DESCRIPTION The NJM567 tone and frequency decoder is a highly stable phase locked loop with synchronous AM lock detection and power output circuitry. Its primary function is to drive a load whenever a sustained frequency within its detection band is present at the self-biased input. The bandwidth cebter frequency, and output delay are independently determined by means of four external components. ■ PACKAGE OUTLINE NJM567D NJM567M ■ FEATURES ● Operating Voltage (4.75V to 9.0V) ● Wide frequency range (0.01Hz to 500kHz) ● High stability of center frequency ● Independently controllable bandwidth (up to 14 percent) ● High out-band signal and noise rejection ● Logic-compatible output with 100mA current sinking capability ● Frequency adjustment over a 20 to 1 range with an external resistor ● Package Outline DIP8, DMP8 ● Bipolar Technology ■ PIN CONFIGURATION ■ BLOCK DIAGRAM NJM567D NJM567M PIN FUNCTION 1 OUTPUT FILTER 2 LOW-PASS FILTER 3 INPUT 4 V+ 5 TIMING R 6 TIMING CR 7 GROUND 8 OUTPUT Ver.2003-12-09 -1- NJM567 ■ ABSOLUTE MAXIMUM RATINGS PARAMETER Supply Voltage SYMBOL V+ Input Positive Voltage VIP Input Negative Voltage VIN Output Voltage V8 Power Dissipation PD Operating Temperature Range Topr Storage Temperature Range Tstg RATINGS 10 V++0.5 -10 15 (Pin8) (DIP8) 500 (DMP8) 300 -40 to +85 -40 to +125 (Ta=25°C) UNIT V V Vdc Vdc mW mW °C °C ■ ELECTRICAL CHARACTERISTICS PARAMETER SYMBOL...
