Integrated Circuit
Digital Tuning System Interface for TV Systems
Description:
The NTE7019 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.
Features:
D All–in–One Chip Incorporating the Peripheral Blocks of the PLL System
D Built–In Synchronized Separate for Channel Detecting Circuit
D Externally Controllable Channel Detection Level
D High Current Low–Saturation–Voltage Band Switch Output: V_O(sat) = 0.3V Typ @ I_OH = –40mA
D Built–In Channel Tuning Voltage: 34V Typ
Absolute Maximum Ratings: (T_A = +25°C unless otherwise specified)
