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.

Use as single-point ground.
+3.3V of power supply.
Connect to ground of power supply.
Serial input positive/negative differential serial input. Connect
SDIn to ground reference via termination network. External
75Ω resistors are required.
Serial output positive/negative differential serial output.
Output has a swing of 2x370 mV and has 50Ω on-chip
termination resistors to internal VDD (1.2V).
Uplink signal. (Low = 0V, High = 1.2V). When driving from
3.3V, an external series resistance of 6.2 kΩ is required.
Connect to ground with a 1 kΩ resistor, defining the uplink
amplitude to 150 mV.
