STMicroelectronics STEVAL-CCA014V1

Overview

STEVAL-CCA014V1 from STMicroelectronics is a demonstration board built around the TSH345 triple video buffer IC, designed for HD video signal conditioning with RGB, Y-Pb-Pr, Y-C-CVBS, and HD line driving capability; features 3×6 dB matched amplifiers, internal 36 MHz low-pass filters per channel, DC level shifters, and 150 Ω load drive capability on AC/DC-coupled outputs.

For engineers reviewing the STEVAL-CCA014V1 datasheet, STEVAL-CCA014V1 pinout, STEVAL-CCA014V1 application, or STEVAL-CCA014V1 equivalent, this board enables rapid evaluation of single-supply (4.5–5.5 V) high-definition video buffering, filter response validation, standby mode behavior, and input multiplexing functionality in broadcast, set-top box, and professional AV equipment prototyping.

Technical Context

The board implements the TSH345's triple-channel architecture with independent 6 dB gain stages and integrated 36 MHz low-pass filters to meet HD video bandwidth requirements while suppressing harmonics. Each channel includes an internal DC level shifter, eliminating external coupling capacitors at inputs.

Input multiplexing (FS0/FS1 control) allows selection among multiple video sources per channel, and standby mode reduces power consumption during inactive periods. All outputs are specified for direct drive into 150 Ω loads under 5 V supply conditions.

FAQ

What video standards does STEVAL-CCA014V1 support?

The board supports RGB, Y-Pb-Pr, Y-C-CVBS, and HD line driving via the TSH345's triple-channel architecture. Each channel includes a 36 MHz low-pass filter and 6 dB gain optimized for analog HD video bandwidth and impedance matching to 150 Ω transmission lines used in broadcast and professional video equipment.

Does STEVAL-CCA014V1 require external input coupling capacitors?

No. The TSH345 IC on the board integrates a DC level shifter on each input channel, enabling direct connection of DC-coupled video sources without external AC-coupling capacitors. This simplifies signal path design and improves low-frequency response stability in RGB and component video applications.

Can STEVAL-CCA014V1 operate from a 3.3 V supply?

No. The TSH345 requires a 4.5–5.5 V single supply, and the board is designed exclusively for 5 V operation. Testing was performed at 5 V, and performance specifications-including 150 Ω load drive and harmonic distortion-are guaranteed only within this voltage range.

Is STEVAL-CCA014V1 still in active production?

No. STEVAL-CCA014V1 is marked as obsolete in ST's official documentation (Doc ID 15862 Rev 1, June 2009). While Aetrix Electronics maintains limited legacy stock for design continuity, no new manufacturing or long-term supply commitment exists from STMicroelectronics.
