说明

The TLK4250 device is a four-channel, multi-gigabit transceiver used in high-speed bidirectional point-to-point data transmission systems. The four channels in the transceiver are configured as four separate links. The transceiver supports an effective serial interface speed of 1.0 Gbps to 2.5 Gbps per channel, providing up to 2.25 Gbps of data bandwidth per channel.

The primary application of the transceiver is to provide high-speed I/O data channels for point-to-point baseband data transmission over controlled impedance media of approximately 50 . The transmission media can be a printed-circuit board, copper cables, or fiber-optic cable. The maximum rate and distance of data transfer depend on the attenuation characteristics of the media and the noise coupling to the environment.
