The datasheet for NJM2206 is introduced in this document.
The NJM2206 is a low‑power IF/AF PLL circuit designed for narrow‑band FM receivers. It integrates a single or double‑balanced mixer‑IF amplifier, detector, and provides high signal‑to‑noise ratio and channel separation. The device operates with a first IF input frequency up to 25 MHz and a second IF at 800 kHz, making it suitable for CB transceivers, wireless control systems, and other communication applications.
The datasheet lists the electrical characteristics, pin configuration, and absolute maximum ratings. Key specifications include a 10 V supply voltage, 2.8 mA operating current at 7 V, and a DIP20 package. Detailed graphs illustrate the frequency response, loop filter behavior, and PLL demodulation performance.
