TRANSMISSION MEDIA
The Ser/Des chipset is intended to be used over a wide variety of balanced cables depending on distance and
signal quality requirements. The Ser/Des employ internal termination providing a clean signaling environment.
The interconnect for FPD-Link III interface should present a differential impedance of 100 Ohms. Use of cables
and connectors that have matched differential impedance will minimize impedance discontinuities. Shielded or
un-shielded cables may be used depending upon the noise environment and application requirements. The
chipset's optimum cable drive performance is achieved at 43 MHz at 10 meters length. The maximum signaling
