Note:
The EQCO30R5 video equalizer can be used in combination with the EQCO30T5 cable driver. This device is capable of receiving the uplink signal whilst other key parameters remain compliant to SMPTE specifications. Please refer to the Microchip web site (www.microchip.com) for the EQCO30T5 data sheet.
Introduction
The EQCO30R5 is a video equalizer for 3G/HD/SD-SDI video, with speeds up to 2.97 Gbps. It is designed to be a direct replacement for competing video equalizers. In addition to downlink functionality from camera to frame grabber, it can also transmit a 5 Mbps uplink signal from the frame grabber to the camera. Additionally, power can be provided over the same cable using the same chip and a few external components. The device operates with 8B/10B coded signals up to 3.125 Gbps.

Typical Link Performance
Table 1, Table 2, and Table 3 give an overview of video equalizer typical performance at room temperature without using the uplink and without providing power over the same coax. When providing power or using the uplink communication to the camera, a small length penalty may arise (in cable length, typically 10%) due to added parasitics and noise. The uplink operates to at least 400m at the 5 Mbps bit rate.
