Reference design for wireless optical comms
A new technology from Texas Instruments dramatically cuts the cost and complexity of bringing the high-speed datarates of optical networking to end users.
The OPA360 is compatible with DACs embedded in video processors, including TI's digital media processors.
The input voltage range includes ground which allows the embedded video-DAC to be DC-coupled into the OPA360.
"The OPA360 provides excellent video performance for either AC-coupling or DC-coupling to the video load", said Frank Haupt, Strategic Marketing Engineer of TI's high-performance amplifier products.
"For AC-coupled outputs, the SAG-correction feature significantly reduces the big and expensive coupling capacitors required by standard video circuits".
"For DC-coupling, the OPA360 uses an integrated level shifter to prevent the output from clipping even when the lowest sync-pulse level on the input is 0V".
An internal DAC reconstruction filter removes out-of-band (5MHz) sampling artefacts.
In shutdown mode, the quiescent current is reduced to less than 5uA, dramatically reducing power consumption and extending battery life.
The OPA360 is available now in the 2 x 2.1mm SC70-6 package from TI and its authorised distributors.
The device is priced at $0.49 in 1000-piece quantities (suggested resale pricing).
Related low-voltage video amplifier products, the OPA355 and OPA357, are also available.
The OPA358, a companion product to OPA360, will be available in 4Q 2004.
