NXP Semiconductors TDA9845
The TDA9845 is a stereo/dual sound processor for TV and VTR sets. Its identification ensures safe operation by using internal digital PLL technique with extremely small bandwidth, synchronous detection and digital integration (switching time maximum 2.1 s; identification concerning the main functions). They are related to the SCART norm.| Part No. | TDA9845 |
