description
The SN65LVDS22 and SN65LVDM22 are differential line drivers and receivers that use low-voltage differential signaling (LVDS) to achieve signaling rates as high as 400 Mbps. The receiver outputs can be switched to either or both drivers through the multiplexer control signals S0 and S1. This allows the flexibility to perform splitter or signal routing functions with a single device. The TIA/EIA-644 standard compliant electrical interface provides a minimum differential output voltage magnitude of 247 mV into a 100- load and receipt of 100 mV signals with up to 1 V of ground potential difference between a transmitter and receiver. The SN65LVDM22 doubles the output drive current to achieve LVDS levels with a 50- load.

The intended application of these devices and signaling technique is for both point-to-point baseband (single termination) and multipoint (double termination) data transmissions over controlled impedance media. The transmission media may be printed-circuit board traces, backplanes, or cables. (Note: The ultimate rate and distance of data transfer is dependent upon the attenuation characteristics of the media, the noise coupling to the environment, and other application specific characteristics). The SN65LVDS22 and SN65LVDM22 are characterized for operation from 40°C to 85°C.

Stresses beyond those listed under "absolute maximum ratings" may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated under "recommended operating conditions" is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability. NOTES: 1. All voltage values, except differential I/O bus voltages, are with respect to network ground terminal. 2. Tested in accordance with MIL-STD-883C Method 3015.7.
