Two devices from Parade Technologies bridge the transition from LVDS to DisplayPort interfaces in notebook and computers. The PS8615 DisplayPort-to-LVDS converter IC converts single or dual link DisplayPort inputs into single or dual link LVDS outputs, supporting display resolutions up to 1920x1200 (at 60Hz). The PS8612 converts a single lane DisplayPort signal to LVDS, which supports display resolutions up to 1680x1050 (at 60Hz). OEMs can mix and match computer chipsets and display panels to optimise price and performance. Both devices require only a single 3.3V supply. They have an on-chip voltage-switching regulator to power 1.2V core circuitry, eliminating the need for external regulators and power consumption is less than 200mW in typical applications. Both devices also incorporate the company's crystal-free technology, eliminating the need for an external crystal or clock reference. The ICs are compatible with VESA DisplayPort specification 1.1a, and the Embedded DisplayPort specification version 1.2. Both devices support DisplayPort link rates up to 2.7Gbit/s and LVDS clock rates up to 135MHz. The company believes it is the first to adopt eDP v1.2 backlight control into a DisplayPort-to-LVDS converter for the ICs to generate the backlight control pulse width modulation signal under control of the GPU, using the eDP v1.2 AUX channel control commands.
