The TC9171P, TC9172P and TC9182P-1 are high‑speed PLL‑LST integrated circuits designed for digital tuning systems. They feature a built‑in prescaler, accept up to 120 MHz input, and provide both pulse‑swallow and direct‑dividing modes for FM, AM and other bands. The devices are offered in a high‑function DIP‑22 package and a conventional DIP‑16 package, each with a range of general‑purpose I/O terminals.
The document provides electrical characteristics, pin assignments, terminal connections, and example application circuits. Key parameters include supply voltage 4.5‑5.0 V, supply current 15‑25 mA (FM), and operating frequency ranges up to 140 MHz for FM and 30 MHz for AM (HF). Serial I/O ports allow configuration of frequency division numbers and other functions.
