High-speed interfaces display
flexibility
Low-power devices support data signalling rates up to 2.7Gbit/s to accommodate DisplayPort and high-definition multimedia interface (HDMI) speeds.
Texas Instruments has introduced three compact DisplayPort devices that provide connectivity between personal computers and video displays The low-power devices support data signalling rates up to 2.7Gbit/s to accommodate DisplayPort and high-definition multimedia interface (HDMI) speeds, commonly used to link desktop and notebook PCs and docking stations to DLP projectors, computer monitors and digital TVs

RF platform brings three radios together
Texas Instruments has developed the industry's first solution that integrates mobile WLAN (mWLAN), Bluetooth and FM stereo audio all in a space-saving platform for mobile phones.
The SN75DP122, SN75DP128 and SN75DP129 all provide one dual-mode DisplayPort input and flexible outputs to enable connectivity between a range of devices.
Dual-mode is the ability of the graphics processor unit (GPU) to transmit either DisplayPort or HDMI/DVI data over the DisplayPort signal lines while supporting the required control signals.
The SN75DP129 translator has one dual-mode DisplayPort input and one transition-minimised differential signalling (TMDS) output.

Video decoder combines four in one
A new analogue-to-digital video decoder combines four independent video decoders into a single chip.
This device can function as a DisplayPort to HDMI/DVI dongle convertor for external attachment to Notebook PCs.
This will enable end users to connect laptops with DisplayPort outputs to monitors with DVI inputs.
The translator can also be used in applications that display PC video data on digital TVs.
The SN75DP128 is a high-performance switch with one DisplayPort input to one of two DisplayPort outputs.
This device can be used in conjunction with laptop docking stations.
It allows the GPU to direct video data either through the docking station connector or to a DisplayPort edge connector.
The SN75DP122 features one DisplayPort input to either a DisplayPort or a level translated TMDS output, allowing flexible connection to either a monitor or a TV.
On this device, the auxiliary port can be configured as an I2C port with an integrated I2C repeater, which is required for HDMI operation.
Both the SN75DP128 and SN75DP122 support switching of the bidirectional auxiliary, hot plug detect (HPD) and cable adapter detect channels.
An integrated level-shifter for the HPD line is provided, which avoids the need to use additional components.
The pinouts of all three devices are optimised for easy flow-through printed circuit board layout.
In addition to these DisplayPort devices, TI offers a broad array of electrostatic discharge protection solutions and low-power video switches such as the TS3DV421, which are fully compliant with the HDMI and DisplayPort standards.
They contribute to TI's broad interface product offering including families of products for M-LVDS, LVDS, CAN, RS485 and PCI-Express standards.
The SN75DP122 and SN75DP128 are available now from TI and its authorised distributors in 56-pin QFN packages.
Suggested resale pricing is US $1.90 and $1.65, respectively.
The SN75DP129 is available now in a 36-pin QFN package with suggested resale pricing at US $1.30.
All pricing is in 1000-piece quantities.
