Since its inception in the early 80's, digital broadcast is quickly becoming the preferred video format. The advantages of the digital format are many. Digital is very stable minimizing equipment adjustments. Copies or reproductions retain the quality of the original. Signal degradation is virtually eliminated, and noise immunity is greatly improved.
Digital video is transmitted over a cable in either a parallel or serial format.
These cables are limited to a transmission distance of less than 30 meters. The newest technology to hit the Broadcast market is Serial Digital Video. The Serial format transmits each bit of the digital word one after another, or serially, over a single coax. Because of the high frequencies involved, impedance tolerance, stable high frequency response and shielding become critical factors, making precision video cables a must in these applications. To provide for maximum performance in applications demanding higher frequency technology, Belden has a Low Loss Serial Digital coax.
