Santa Clara, Calif.National Semiconductor Corp. has added five extended-temperature single and dual transmitters and receivers to its LVDS product portfolio that are optimized for driving signals through cable harnesses in systems operating in harsh, high-temperature environments, such as automotive, industrial and military applications.
The DS90LV011AH transmitter, DS90LT012AH receiver, DS90LV027AH dual transmitter, DS90LV028AH dual receiver and DS90LV049H integrated dual transceiver are guaranteed to operate in environments up to 125°C.
"Designers of high-performance industrial systems were once limited to lower-speed communication standards like RS-485 and CAN for data transport," said Jeff Waters, product line director for the Interface division at National, in a statement. "National's new extended temperature LVDS PHYs will enable ten times the level of performance of lower-speed communication standards, driving data rates up to 400-Mbits/s over cables in very hot and electro-magnetically noisy environments."
In a typical application, the LVDS physical layer devices (PHYs) improve signal integrity by translating the single-ended control and data signals from sensors into LVDS signals for transmitting to the digital processor, typically an FPGA or ASIC. The DS90LV011AH transmitter, DS90LT012AH receiver, DS90LV027AH dual transmitter, DS90LV028AH dual receiver and DS90LV049H integrated dual transceiver functions use the LVDS analog interface to provide a high-performance signal path that transfers digital information. In addition, the DS90LT012AH features an integrated LVDS input termination to save board space. The DS90LV027AH and DS90LV028AH feature a flow-through pin-out to simplify board layout.
All of the LVDS PHYs are offered in extremely small packages to minimize board space. The DS90LV011 and DS90LT012 are packaged in a 5-pin SOT-23. The DS90LT012 is also available as a bare die. The DS90LV027 and DS90LV028 are packaged in an 8-pin SOIC and the DS90LV049 is packaged in a 16-pin TSSOP. Lead-free package options are also available.
Available now in 1,000-unit quantities, the DS90LV011AH is priced at 46 cents each, the DS90LT012AH is 38 cents each, the DS90LV027AH is 78 cents each, the DS90LV028AH is $1.08 each and the DS90LV049H is 90 cents each.
