Breakthrough performance in DisplayPort and HDMI switches

September 05, 2012 // By Nick Flaherty
NXP Semiconductors has launched two high-performance switches supporting DisplayPort and HDMI architectures.

The CBTL06DP213 is a bi-directional switch for DisplayPort 1.2 applications featuring industry-leading bandwidth over 11GHz while the CBTL06GP212, the industry’s first switch to enable simultaneous support for both DisplayPort 1.2 and HDMI 1.4. Both are multi-channel capable devices designed using NXP’s high-bandwidth analog pass-gate technology.
“DisplayPort and HDMI have evolved to support very high-bandwidth audio/visual applications, and OEMs worldwide are embracing these standards in computing systems, mobile devices and displays,” said Grahame Cooney, general manager, high-speed interfaces and clocks, watches and graphics drivers at NXP Semiconductors. “By delivering extremely high speeds and excellent performance, NXP’s interface components are enabling the design of high-performance DisplayPort and HDMI systems meeting rigorous OEM requirements. With the CBTL06GP212, we’re also enabling exciting new combo connectors that provide all-in-one support for both DP and HDMI.”
The CBTL06DP213 is NXP’s third-generation high-performance DisplayPort multiplexer featuring extremely high bandwidth exceeding 11GHz, as well as excellent signal integrity characteristics with exceptionally low return loss. By minimizing signal degradation, the CBTL06DP213 also minimizes the number of active components required in connectors and cables connecting PCs, notebooks and tablets with external monitors, docking stations and other peripherals. The CBTL06DP213 supports DP 1.2, DP 1.1a and eDP (embedded DisplayPort) operating at 5.4Gbps, 2.7Gbps or 1.62Gbps. NXP has collaborated with key customers to define key parameters and to achieve excellent signal integrity performance on customer products at the platform level.
The CBTL06GP212 is a new six-channel switch for DisplayPort, HDMI and PCI Express applications at Gen2 speeds – 5.0Gbps for PCI Express, 5.4Gbps for DisplayPort, and 3.4Gbps for HDMI. Featuring an exceptionally wide common-mode voltage range (3.6V) and low insertion loss, the CBTL06GP212 is the industry’s first switch to enable simultaneous DisplayPort 1.2 and HDMI support, reducing the number of additional components required, and enabling the design of compact combo connectors.
The CBTL06GP212 provides four differential channels capable of 1:2 switching; 2:1 multiplexing of bi-directional, AC-coupled PCI Express or DisplayPort signals;
