Analog Devices’ Multipoint LVDS Transceivers Deliver Industry’s Highest ESD Protection for High-speed, Multi-node Applications
Analog Devices, Inc. today introduced a series of multipoint, low-voltage, differential signalling transceivers with the highest ESD protection of any multipoint LVDS transceivers. The ADN469xE M-LVDS series includes eight transceivers, each of which is capable of connecting 32 data/clock nodes using a single differential cable pair at data rates of 100 Mbps or 200 Mbps.
Traditional LVDS communication links, by comparison, must use 32 separate point-to-point nodes, which significantly increases power, connector size, cabling costs and total board space. ADI’s ADN469xE M-LVDS series delivers 8 kV IEC ESD protection, offering up to 11 times the protection of competing M-LVDS transceivers. This higher level of protection improves the reliability of insertable/removable boards and cards used in wireless base station and networking infrastructure, data acquisition, automated test equipment and other high-speed, highly networked backplane and cable applications.
Available in half- and full-duplex versions, ADI’s ADN469xE transceivers are fully compliant with the TIA/EIA-899 M-LVDS standard. The new transceivers are available in configurations that include:
•ADN4691E/ADN4693E : Type 1 receivers with 200 Mbps data rates include symmetrical input threshold voltage and are designed to improve clock timing performance
•ADN4696E/ADN4697E: Type 2 receivers with 200 Mbps data rates are designed for data applications and feature a receiver-input threshold voltage offset of –100 mV. This ensures a known receiver output state when the bus is idle (bus-idle fail-safe) or the bus inputs are open (open-circuit fail-safe).
ADN469xE M-LVDS Transceiver Series Key Features:
•ESD protection: 15 kV HBM, 8 kV IEC61000-4-2 contact discharge
•–1 V to 3.4 V common mode range
•Enhanced PSRR (for system jitter performance)
•Enhanced differential noise rejection on receiver input
•Temperature range: –40˚C to 85˚C
