The device uses a 5-V supply and is designed to interface with two pairs of telephone-grade twisted-pair cables coupled through isolation transformers.
The functional components of the device include a differential receiver and driver, receiver squelch with noise filter, jabber controls, collision detection, data link monitor, and signal quality error (SQE) testing.
The LinBiCMOS process technology is used in the device design to ensure analog precision, low power, and high-speed operation.
The device contains an elaborate receiver-squelch circuit† that provides an improved level of noise rejection by qualifying the incoming signal stream with three different criteria.
First, the signal is compared to a set threshold voltage level.
Then, the pulse duration is compared to a set time window.
Last, the signal must follow a set pattern of positive and negative pulses before the circuit finally opens the receiver chann...
