Parade Technologies Ltd.'s PS8615 offers a way to convert single or dual link DisplayPort inputs into single or dual link LVDS outputs, with support for display resolutions up to 1920x1200 at 60Hz. Meanwhile, another device, the PS8612, converts a single lane DisplayPort signal to LVDS, supporting display resolutions up to 1680x1050.

Jimmy Chiu, VP of marketing at Parade Technologies, explained that the devices address the move toward DisplayPort from LVDS among notebook manufacturers. "Our two new conversion devices permit OEMs to mix-and-match computer chipsets and display panels to optimize price and performance in individual systems," he said.

The two devices, both of which require a single 3.3V power supply, integrate an on-chip voltage-switching regulator to power a 1.2V core circuitry, thus negating the need for external regulators and reducing power consumption. Typical applications consume less than 200mW. Parade uses its crystal-free technology to manufacture the devices, which means an external crystal or clock reference is no longer needed.

The PS8612 and PS 8615 are fully compatible with VESA DisplayPort specification 1.1a and Embedded DisplayPort (eDP) specification version 1.2. They also support DisplayPort link rates up to 2.7Gb/s and LVDS clock rates up to 135MHz. The devices support DisplayPort or eDP with no-link training, fast-link training and full-link training.
