National Semiconductor Launches LVDS Buffer with Low Signal Jitter and High ESD Protection

National Semiconductor's LVDS transmitters and receivers are suitable for harsh environments National Semiconductor Corporation (National Semiconductor Corporation) recently announced the launch of five new single-channel and dual-channel transmitters and receivers with a wider temperature range. These general-purpose LVDS physical layer (PHY) chips can still drive signals through cables even in extremely harsh high-temperature environments, making them suitable for automotive electronic systems, industrial equipment and military facilities. The five chip models are DS90LV011AH transmitter, DS90LT012AH receiver, DS90LV027AH dual-channel transmitter, DS90LV028AH dual-channel receiver, and DS90LV049H highly integrated dual-channel transceiver, all of which are guaranteed to operate in temperature environments up to 125°C. These five new products not only have extremely low power, but also have good LVDS signal driving capabilities and data transmission speeds of up to 400Mbps. In addition, their ability to resist noise interference is also good. These LVDS physical layer chips can convert single-ended control signals and data signals from sensors into LVDS signals, and then transmit them to FPGAs or special application integrated circuits, such as digital processors. This signal conversion process helps to improve signal integrity. Automotive and industrial systems are often subject to electronic noise interference, and LVDS is an ideal signal transmission technology for such applications. The five new single-channel and dual-channel transmitters and receivers with wide temperature ranges all support the differential LVDS interface standard and are suitable for temperatures ranging from -40°C to +125°C. The DS90LV011AH transmitter, DS90LT012AH receiver, DS90LV027AH dual-channel transmitter, DS90LV028AH dual-channel receiver, and DS90LV049H highly integrated dual-channel transceiver all use the LVDS analog interface as a high-performance signal path to transmit digital data. In addition, the DS90LT012AH chip has the LVDS input terminal device built into the chip to save board space. Both the DS90LV027AH and DS90LV028AH chips have flow-in pinouts to help streamline circuit board design. All of the above LVDS physical layer chips are packaged in very small packages. Both DS90LV011AH and DS90LT012AH chips are packaged in 5-pin SOT-23. DS90LT012AH chips are available in unpackaged bare chips. DS90LV027AH and DS90LV028AH chips are packaged in 8-pin SOIC, while DS90LV049H chips are packaged in 16-pin TSSOP. In addition, all of the above chips are available in lead-free packages. All of the above chips are purchased in units of 1,000 pieces and are available in large quantities. The unit price of DS90LV011AH is $0.46, the unit price of DS90LT012AH is $0.38, the unit price of DS90LV027AH is $0.78, the unit price of DS90LV028AH is $1.08, and the unit price of DS90LV049H is $0.90.
