NTE15042 Integrated Circuit Digital Tuning System Interface for TV Systems
Description: The NTE15042 is an integrated circuit in a 16-Lead DIP type package developed to facilitate the Phase Lock Loop (PLL) digital tuning system interface for TV systems. Since all the peripheral blocks are incorporated into this device, the number of peripheral parts can be greatly reduced.
