LVDS product portfolio continues to growLow Voltage Differential Signaling (LVDS) technology can expand into new applications with the introduction of four LVDS devices from Texas Instruments. Two of the devices, the SN65LVDS050 and SN65LVDS051, are dual driver/receiver products that contain two drivers and two receivers. The ’LVDS050 comes with an enabling scheme that allows designers to operate only the drivers, only the receivers or all the drivers and receivers. The ’LVDS051 comes with an enabling scheme for the drivers only. Designers can choose to operate both drivers or only one driver — in addition to the two receivers onboard. Each of the other two devices, the SN65LVDS179 and the SN65LVDS180, has a single driver/receiver. The ’LVDS180 also comes with an enabling scheme that allows designers to use the device as a single driver, a single receiver or as a driver and a receiver. The new LVDS devices have ESD protection of 8kV on the bus pin and operate off of a single 3.3-V power supply but are tolerant up to 5-V on the I/O pins. They feature a driver propagation delay of less than 2.5 nanoseconds. Each receiver supports open-circuit fail safe to prevent noise from appearing as a valid signal. The devices are scheduled to be available in 4Q98. TI has added four other devices to its LVDS portfolio. The new quad driver and receiver, SN65LVDS3487 and SN65LVDS3486, have enablers that allow the drivers and receivers to be turned on in pairs. This characteristic differentiates them from the previously released SN65LVDS31 and SN65LVDS32, which had to have all four drivers and receivers enabled at once. The new dual driver and receiver, the SN65LVDS9638 and SN65LVDS9637, respectively, have the same innovative characteristics as the quad drivers and receivers, with the only difference being the number of drivers and receivers per chip. The ’LVDS9638 and ’LVDS9637 follow the pin-configuration of uA9638 and uA9637, the industry’s standard.
