Parade technologies Unveils Latest Video Interface Converters with Jitter Cleaning Capability

By CIOReview | Friday, August 21, 2015

SANTA CLARA, CA:  Parade Technologies, a provider of video display and high speed interface IC solutions, announces addition of two new video interface converters to the company’s video protocol conversion product suite.

The latest video interface converters, PS175 and PS 176, are developed for motherboard applications and protocol adapters respectively. Both devices support maximum HDMI 2.0a data rate of 6Gbit/sec enabling 4K UHD performance at 60fps and 24bits-per-pixel color with 4:4:4 color sampling. The ability to perform “jitter cleaning” during conversion process is the key feature that differentiates these two devices from other solutions. Intrinsic jitter from the DisplayPort (DP) Source and as well jitter ingress and ISI generated jitter from the DisplayPort transmission line can be removed by the PS175 and PS176 during the protocol conversion process resulting in a clean, low-jitter HDMI 2.0a output.

Key features include support for resolution up to 4096x2160 at 60Hz frame rate with 24-bit color, stable HDMI output signal with wide compliance margin, on-chip microprocessor with internal SPI ROM, support for external crystal or reference clock along with internal crystal oscillator.

The devices also supports all the DP to HDMI protocol conversion requirements specified by the VESA DisplayPort Standard, version 1.3, and the VESA DisplayPort Alternate Mode over USB Type-C Standard, version 1.0a on the input side. HDMI output backs SCDC (Status and Control Data Channel), TMDS scrambling, and the CEC receptacle interface.


The PS175 is optimized for motherboard applications. It is crafted to be used with a DP1.2 or 1.3 input allowing it to output HDMI2.1a.  The PS175 provides anonymous, automatic operation enabled by an integrated microprocessor that uses an internal SPI ROM for configuration and microcode.


The PS176 is suitable for cable adapters, television receivers, monitors and other video protocol conversion applications. The device accepts any DP input format including DP 1.1a, DP 1.2 or DP 1.3 and converts into HDMI and DVI video modes along with HDMI 2.0a format. It can be applied in DP to HDMI active protocol converters, DP Alt Mode over USB Type C to HDMI protocol converters. The device can also be used in DP input on television receivers and monitors.
