Note:
The EQCO30T5 cable driver can be used
in combination with the EQCO30R5 video
equalizer. This device is capable of
transmitting the uplink signal whilst other
key parameters remain compliant to
SMPTE specifications. Please refer to the
Microchip web site (www.microchip.com)
for the EQCO30R5 data sheet.
Introduction
The EQCO30T5 is a video cable driver for 3G/HD/SDI
video, with speeds up to 4.0 Gbps. It is designed to be
a direct replacement for competing cable drivers. In
addition to downlink functionality from camera to frame
grabber, it can also receive 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 and with SMPTE
signals up to 2.97 Gbps.

+3.3V of power supply.
Enables the output driver pins.
Do not connect; leave floating. Used for internal testing.

Serial negative cable driver output with 50Ω on-chip serial
output resistance. Complement with 25Ω externally.
Serial positive cable driver output with 50Ω on-chip serial
output resistance. Complement with 25Ω externally.
Digital output signal of the full-duplex uplink.
Disables input trace equalization.
1.1.1 SDIP/SDIN
SDIp/SDIn together form a differential input pair.
Between SDIp and SDIn inputs, there is a
termination resistor of 100Ω. The intention is to
always use AC coupling. When AC-coupled, the
common-mode gets biased to 600 mV.
1.1.2 RREF
A resistor is to be connected between VCC and the
Rref pin. A resistor of 750Ω gives an 800 mV launch
amplitude in the 75Ω coaxial cables. A larger resistor
gives a smaller amplitude.
1.1.3 ENABLE
When enable is floating or pulled high, the output
driver is enabled. When enable is low, the output is
disabled and power consumption drops significantly.
