Raleigh, N.C.austriamicrosystems AG has unveiled the first products in its new family of low-voltage differential signaling (LVDS) ICs that offer a 500-Mbits/s data rate with only a 300-ps (pulse skew).
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 are said to halve the supply current of competing products, improving the power consumption of LVDS interfaces.
The AS1150/51 receivers consume a supply current of 5-mA while the AS1152 driver consumes 4-mA. 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 a pulse skew of 300ps for the receivers and 350ps for the driver, the devices are suitable 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 0.3-mA for AS1150/51 and to 3.5-mA 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 +3.3-V supply, and is available in a 16-pin TSSOP package.
The AS1150-52 is priced at $1.52 each in 1,000-unit quantities.
