PA1001A datasheet

Description

The PA1001A series preamplifiers / signal conditioners and converters are suitable for use with either magnetic or RF type pickup coils and allow convenient interfacing with the process measuring devices and digital electronics. When used with Magnetic type pickups they accept low level signals and produces a pulse output, while providing rejection of unwanted noise and false signals.

A RF type pickup reduces the pickup drag associated with conventional magnetic pickups, resulting in a significant increase in the usable range. The PA1001A series excite a RF type pickup with a 20KHz signal. Motion of ferrous material is sensed and the motion modulates the coil field and subsequent conditioning provides a pulse output signal.

Description

VIDEO, CHROMA AND SYNCHRONIZING SIGNALS PROCESSING IC FOR PAL / NTSC / SECAM SYSTEM COLOR TV

TB1226EN that is a signal processing IC for the PAL / NTSC / SECAM color TV system integrates video, chroma and synchronizing signal processing circuits together in a 56-pin shrink DIP plastic package. TB1226EN incorporates a high performance picture quality compensation circuit in the video section, an automatic PAL / NTSC / SECAM discrimination circuit in the chroma section, and an automatic 50 / 60Hz discrimination circuit in the synchronizing section. Besides a crystal oscillator that internally generates 4.43MHz, 3.58MHz and M / N-PAL clock signals for color demodulation, there is a horizontal PLL circuit built in the IC.
