SN75061

The SN75061 is a single-channel driver/receiver pair designed for use in IEEE 802.3, 1BASE5 applications as well as other general data communications circuits. The SN75061 offers both a driver and a receiver that are easily configured for use with a variety of controllers and data encoder/decoders.

The SN75061 receiver features a full analog squelch circuit with an adjustable threshold and a programmable squelch delay. Internal nodes of the squelch circuitry are brought out to external connections to allow for the insertion of noise-filtering circuitry of the designer's choice.

As with the SN75061 receiver, the driver offers a variety of implementation options. Driver enabling may be directly controlled by an external logic input or by use of an on-chip one-shot that is retriggered as long as data is being sent to the driver. The driver then automatically goes to the high-impedance state when end-of-packet common phrase occurs. The driver features internal slew-rate control for optimal matching of rise and fall times allowing for reduction of driver-induced jitter.
