Qualitas Semiconductor's eDP RX PHY IP v1.5a is ready for mass production

SEOUL, South Korea – May 24, 2024 — QUALITAS SEMICONDUCTOR CO., LTD. (hereinafter referred to as QUALITAS) (QUALITAS, KOSDAQ: 432720), a leading provider of high-speed interconnection solutions, announces the availability of its silicon-proven eDP RX PHY v1.5a, compliant with the latest standards of display.

Qualitas has expanded its IP portfolio thanks to its success in silicon with its eDP RX PHY line, specifically supporting eDP v1.5a, the latest specification. Previously, Qualitas successfully developed the 14nm eDP v1.4b RX PHY and brought it to mass production in 2022.

Qualitas’ latest eDP RX PHY test chip is manufactured using a 14nm process and plans to continue development using advanced 8nm process technology. It supports speeds ranging from 1.62 Gbps up to a maximum data rate of 8.1 Gbps to accommodate a variety of display resolutions. This PHY uses a digital clock data recovery (CDR) architecture that ensures fast relock times in scenarios such as existing panel self-refresh (PSR) or following an electrostatic discharge event (ESD), thus improving stability and responsiveness.

Main characteristics

Compliant with eDP v1.5a
Max. 8.1Gbps data rate supported.
Adopt digital CDR architecture for fast relock time at PSR output and abnormal conditions due to ESD events.
PSR, PSR2 supported for low power consumption (FW_SLEEP, FW_STANDBY supported)
ALPM with alarm clock without AUX
Adaptive equalization
NO LT supported in PSR exit condition.
Offset calibration supported EOM (Eye Open Monitoring) function supported.
BITS function supported.
Channel and PN exchange supported

The IP PHY is equipped with sophisticated signal integrity tools such as adaptive linear equalizer and feedback equalization to maintain clear and stable image quality under different conditions. The PHY also automates certain processes such as calibrating its analog circuits and correcting any signal offsets, improving consistency and reliability. For troubleshooting and ensuring optimal operation, it incorporates a built-in monitor to check signal clarity and a self-test function that verifies the integrity of data transmission, providing robust performance across a range of applications display.

Qualitas has a history of signing eDP contracts with companies known as leading players in the display market and their eDP v1.5a RX PHY has passed the CTS certification test and is expected to be mass produced in SoCs TCON this year. Qualitas CEO Dr. Duho Kim said: “We have always focused on meeting the changing needs of our customers, including technical support to deliver superior quality. It is our great privilege to continue this great work of developing the most recent specification on TCON standards, including the great success of realizing the eDP v1.5a RX PHY IP.
