Parade Introduces New Jitter-Cleaning Retimer for HDMI 2.1

Posted October 15th, 2019

First Retiming Repeater for HDMI 2.1 includes FRL support up to 12 Gbps to enable 8K and 10K display resolutions

San Jose, Calif.— 15 October 2019 —Parade Technologies, Ltd. (Taiwan OTC: 4966.TWO), a leading high-speed interface, video display, and touch controller IC supplier, today announced another addition to its portfolio of high-speed data interface retimer products. The new PS8419 is the first available retimer chip designed for HDMI 2.1 interface applications.  It removes clock and data jitter, as well as data line skew, that can be imposed on the high-speed HDMI 2.1 signal as it propagates across the HDMI interconnect cable and connectors, and system PCB circuit traces.  Applications for the PS8419 include at the output of an HDMI 2.1 source device to provide a clean output signal at the HDMI receptacle, or at the input of an HDMI 2.1 display or A/V receiver to ensure error-free signal reception capability.

The PS8419, designed for the latest HDMI 2.1 specification, is an encore to Parade’s ever-popular PS8409A that was introduced in 2014 for HDMI 2.0 applications. Compared to the PS8409A, the PS8419 doubles the data rate capability from 6 Gbps (Gigabits-per-second) to 12 Gbps per data lane, as supported by the updated HDMI 2.1 specification. This higher data rate enables the support of 8K and 10K video display timing for the next generation of digital televisions and monitors.

The PS8419 requires no external crystal or clock reference and supports FRL (Fixed Rate Link) signal repeating up to 12 Gbps, and TMDS signal repeating up 6 Gbps.  The device automatically detects the transmission mode to maintain full backward compatibility with HDMI 2.0 and earlier versions of HDMI.  For FRL operation, the interception of SCDC signaling is used to support autonomous interface link training, without the need for any system host support.

“The PS8419 once again underscores Parade’s leadership in high-speed data signal integrity products,” said Jimmy Chiu, Executive VP of Marketing at Parade Technologies. “Based on our past experience with HDMI 2.0 as well as recent OEM customer input, we expect that the doubled data rate of HDMI 2.1 will present an even greater challenge for many video source, display and A/V receiver system implementations.  Demand for the PS8419 has been driven by the challenge faced by OEMs to establish adequate operating and compliance margin at these new higher speeds.  The end goal is to provide a seamless consumer experience in terms of interoperability between devices, even with aging or damaged HDMI cables, for example.”

The PS8419 can accept either a DC or AC coupled HDMI input making it suitable for native signal repeating or use as a level shifter in a personal computer product.  Input receiver equalization is configurable, which allows tuning to compensate for system characteristics. Power down management is automatic based on signal detection. This low power device utilizes 3.3 and 1.1 volt power supplies.


The PS8419 is available in a 4.5mm x 6.5mm 46-pin QFN Halogen free RoHS package. Samples are shipping now.
