National Semiconductor has introduced an eight-member family of automotive-grade low-voltage differential signaling (LVDS) devices, including three 2 x 2 crosspoint switches, a set of single and dual differential drivers and receivers, and a dual line driver and receiver pair. Each device is AEC-Q100 Grade 3 certified and guaranteed to operate at up to 85°C.
LVDS technology provides low power operation, high bandwidth, and exceptional noise immunity, and generates very little electromagnetic interference (EMI). National said its PowerWise crosspoint devices, which consume as little as 105 mW of power per-channel, combine with National’s line drivers and receivers to reduce power consumption and heat dissipation in applications including infotainment, instrument cluster displays, GPS navigation, and backup and lane departure camera warning systems.
The PowerWise DS25CP102Q 2 x 2 LVDS crosspoint switch delivers 6 ps typical jitter performance at data transmission rates up to 3.125 Gbps. The device features selectable transmit pre-emphasis and receive equalization to extend signal transmission reach in cables and FR-4 backplanes. It’s packaged in a 16-pin LLP. Additional information is available at www.national.com/pf/DS/DS25CP102Q.html.
The PowerWise DS25CP152Q 2 x 2 LVDS crosspoint switch is identical in performance and packaging but does not include signal conditioning. Information is available at www.national.com/pf/DS/DS25CP152Q.html. The DS10CP152Q 2 x 2 LVDS crosspoint switch, without signal conditioning, provides lower speed (1.5 Gbps) data transmission. Information is available at www.national.com/pf/DS/DS10CP152Q.html. The DS90LV011AQ LVDS differential line driver and DS90LT012AQ LVDS differential line receiver both support switching rates up to 400 Mbps (200 MHz). Both devices are supplied in 5-pin SOT-23 packages. Information is available at http://www.national.com/pf/DS/DS90LV011AQ.html and http://www.national.com/pf/DS/DS90LV011AQ.html . The DS90LV027AQ LVDS dual differential line driver supports switching rates up to 600 Mbps (300 MHz), while the DS90LV028AQ LVDS dual differential line receiver and DS90LV049Q LVDS dual line driver and receiver pair each support switching rates up to 400 Mbps (200 MHz). The DS90LV027AQ and DS90LV028AQ are supplied in 8-pin SOIC packages and the DS90LV049Q is supplied in a 16-pin TSSOP package.
