CYV270M0104EQ-LXC

Specialized Overview

The CYV270M0104EQ is an adaptive video cable equalizer designed to restore signals received over 75 Ω coaxial cable. It meets SMPTE 259M data rates and supports DVB-ASI at 270 Mbps, with multi-standard operation from 143 Mbps to 360 Mbps. The device utilizes Cypress CLEANLink technology and is optimized to equalize up to 350m of Belden 1694A or Canare L-5CFB coaxial cable at 270 Mbps. It features a single 3.3V supply, consuming typically 160 mW (max 190 mW) power. The component operates within a commercial temperature range of 0°C to +70°C and is housed in a 16-pin Quad Flat Pb-free (QFN) package.

Specialized Procurement Notes

Verify the specific ordering suffix against official documentation to confirm package type and operating range. Ensure that the procurement channel provides genuine components from authorized sources. Confirm RoHS compliance status if required by local regulations. Check for any specific handling requirements related to electrostatic discharge protection during storage and installation.

Specialized Selection Notes

Select this component when equalizing standard definition video signals over extended distances using 75 Ω coaxial cables. It is suitable for applications requiring seamless integration with HOTLink II receivers. Consider the maximum cable length adjust feature for optimizing performance based on specific cable types like Belden 1694A or Canare L-5CFB. Evaluate power consumption constraints as it operates on a single 3.3V supply.

Specialized Part Context

This part belongs to the adaptive video cable equalizer category, specifically designed for professional video applications. It addresses signal degradation issues in long-distance serial digital video transmission. The device complements other Cypress video interface solutions, providing a complete system approach for high-quality video signal integrity over copper cabling infrastructure.

Specialized Replacement Considerations

The datasheet indicates pin compatibility with existing QFN equalizer devices. Verify functional equivalence and pinout alignment before substitution. Ensure that replacement parts support the same data rates and cable lengths. Confirm that thermal dissipation characteristics match the original design requirements.

Specialized FAQ

How does the MCLADJ pin function?

The Maximum Cable Length Adjust (MCLADJ) pin sets the approximate maximum cable length to equalize. When the set length is reached, the Carrier Detect indicator deasserts. If not needed, leave it floating or tied to ground for maximum equalized length.

What is the purpose of the BYPASS pin?

When set HIGH, the BYPASS pin routes the input signal directly to the outputs without equalization or DC restoration. When LOW, the incoming video stream is equalized. This setting is ignored if MUTE is active.

How is automatic muting enabled?

Automatic muting is enabled by connecting the Carrier Detect (CD) output pin directly to the MUTE input pin. This causes the equalizer outputs to mute when the signal is lost or the maximum cable length is exceeded.
