NJM567 TONE DECODER / PHASE LOCKED LOOP GENERAL DESCRIPTION PACKAGE OUTLINE 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. 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 PIN FUNCTION 1 OUTPUT FILTER 2 LOW-PASS FILTER 3 INPUT + 4 V 5 TIMING R 6 TIMING CR 7 GROUND NJM567D 8 OUTPUT NJM567M BLOCK DIAGRAM Ver.2003-12-09 -1- NJM567 ABSOLUTE MAXIMUM RATINGS (T =25C) a PARAMETER SYMBOL RATINGS UNIT + Supply Voltage V 10 V + Input Positive Voltage V V+0.5 V IP Input Negative Voltage V -10 Vdc IN Output Voltage V 15 (Pin8) Vdc 8 Power Dissipation P (DIP8) 500 mW D (DMP8) 300 mW Operating Temperature Range T -40 to +85 C opr Storage Temperature Range T -40 to +125 C stg + ELECTRICAL CHARACTERISTICS (T =25C, V =5.0V) a PARAMETER SYMBOLTEST CONDITION MIN.
