Description

The CS8952-CQ is a high-performance, low-cost electronic component model that falls under the category of Receivers & Transceivers in the product market. It utilizes CMOS technology to deliver a reliable and efficient 100BASE-X/10BASE-T Physical Layer (PHY) line interface. With its adaptive equalizer, it is optimized for noise and near end crosstalk (NEXT) immunity, allowing for receiver operation on cable lengths exceeding 160 m. The CS8952-CQ also boasts an extremely low transmit jitter, reducing link partner performance issues. Additionally, it has minimized transmit driver common mode noise for simplified FCC certification.
