Analog Devices Inc. ADN4680E Quad M-LVDS Transceivers
The Analog Devices’ ADN4680E comprises four multipoint, low voltage differential signaling transceivers that can operate at up to 125 MHz, or 250 Mbps nonreturn to zero.
The driver and receiver of each transceiver are connected in half-duplex configuration, which allows each transceiver to be configured via independent enable pins for either sending or receiving data. ESD protection of up to ±15 kV is implemented on the bus pins.
The transceivers are optimized for low dynamic power consumption for use in high density applications. The ADN4680E is designed to the TIA/EIA-899 standard for use in M-LVDS networks and complement TIA/EIA-644 LVDS devices with additional multipoint capabilities.
The receivers detect the bus state with a differential input of as little as ±50 mV over a common-mode voltage range of −1 V to +3.4 V. Each receiver can be independently pin selectable as a Type 1 or Type 2 receiver.
With M-LVDS, a transmitting node drives a differential signal across a transmission medium such as a twisted pair cable. The transmitted differential signal allows other receiving nodes that are connected along the bus to detect a differential voltage that can then be converted back into a single-ended logic signal by the receiver.
Modern distributed computing systems require smaller modules which must communicate more data over faster backplanes. With precision timing performance for clock and data distribution, and combined with enhanced ESD protection, the ADN4680E ensures reliable and robust systems.
