Low-Voltage Differential Signaling (LVDS) ICs

Description

Unterpremstaetten, Austria (11 July 2006) - austriamicrosystems (SWX: AMS), a leading global designer and manufacturer of analog integrated circuits (ICs) for communication, industrial, medical and automotive applications, has unveiled the first products in its new family of low-voltage differential signaling (LVDS) ICs. Ideal for applications requiring high-speed data transmission, such as digital copiers, laser printers, cellphone base stations, telecom switches, and network switches/routers, the AS1150-52 quad ICs halve the supply current of competing products, improving the power consumption of LVDS interfaces.

With this announcement, austriamicrosystems continues to demonstrate its industry leadership in low power consumption. Offering an outstanding data rate of up to 500Mbps, the AS1150/51 receivers consume a supply current of only 5mA while the AS1152 driver consumes just 4mA.

"In typical applications the LVDS transmission improves noise immunity of data signals, by converting single ended signals into LVDS signals. In applications where electrical disturbances cannot be avoided and high data rates are needed, LVDS is the signalling technology of choice, offering superior breakdown immunity and errorfree data transmission," said Walter Moshammer, marketing director for standard linear at austriamicrosystems. LVDS signal transmission reduces electromagnetic interference (EMI), and is therefore ideal in applications sensitive to electrical disturbances."

Each AS1150/51 receiver accepts four LVDS input signals conforming to the ANSI TIA/EIA-644 LVDS standard, and converts them to low-voltage LVTTL/LVCMOS output levels. The AS1151 features integrated termination, which cuts component count and saves board space by eliminating the need for four external resistors. The AS1152 driver converts four low-voltage LVTTL/LVCMOS signals into LVDS output signals conforming to the ANSI TIA/EIA-644 LVDS standard. Designed with flow-through pin-out, the AS1150-52 family reduces crosstalk between channels and simplifies PC board layout.

With an extremely small pulse skew of only 300ps for the receivers and 350ps for the driver they are ideal for high-resolution imaging and high-speed interconnection applications. With the enable input, all four out- and input pins are set to a high-impedance state, which reduces power consumption to only 0.3mA for AS1150/51 and to 3.5mA for the driver.

Guaranteed to work in a temperature range of -40°C to +85°C the AS1150-52 quad LVDS family operates from a single +3.3V supply, and is available in a 16-pin TSSOP package.
