National Semiconductor Corp. has introduced a high-speed LVDS Serdes chipset that serializes 24bits of data over a single differential pair (2 wires) at a data rate of 1.03Gbps. In addition, this chipset features true embedded clock architecture and a unique random data lock feature.

Unlike other Serdes chipsets that require the system designer to employ a second oscillator at the receiver, the DS90UR241 serializer and DS90UR124 deserializer chipset features true embedded clock architecture to receive data without burdening the system with a second oscillator. This feature reduces system cost and simplifies system design by eliminating the need to match transmit and receive oscillator frequencies.

With the proliferation of flat panel displays in demanding commercial, industrial and automotive applications, system architects need a robust, cost-effective method to drive high-bandwidth video data over long distances. By achieving 1Gbps of bandwidth over a single, low-cost differential pair, National's DS90UR241 and DS90UR124 chipset promises high-quality displays in a variety of applications, including automotive navigation and rear seat entertainment, POS terminals and industrial displays.

For demanding hot-plug applications, the company's Serdes chipset also includes a unique random data lock feature that enables quick recovery from datastream disruptions caused by spurious electrical impulses or momentary mechanical disconnects. While other Serdes chipsets require a training session for the serializer and deserializer to achieve lock, National's chipset locks quickly with any data pattern.

The DS90UR241 is offered in a 48-pin TQFP package and the DS90UR124 is offered in a 64-pin TQFP package. Both are already available. The DS90UR241 is priced at $6.60 and the DS90UR124 at $7 in 1,000-unit quantities.
