The MAX3885ECB+DG126 serializer/deserializer (SERDES) product is a high-performance triple-channel, low-power serializer/deserializer that supports data rates from 1.5 Gbps to 3 Gbps. It integrates the Maxim MAX3885ECB, $V_{DD}=1.8V$ linear deserializer for wide-range deserializing with the Maxim DG126 double-driven equalizer, making it an ideal solution for high-speed serial I/O applications.

The MAX3885ECB+DG126 serializer/deserializer utilizes a deterministic equalizer algorithm to compensate for signal degradation caused by crosstalk, inter-symbol interference (ISI), jitter, pulse-width distortion, and other impairments. It also provides the flexibility needed to maximize the performance of differential signal operations. Additionally, the serializer/deserializer offers enhanced linear operation with superior jitter attenuation characteristics, high-bandwidth recirculation, and implementation of equalization equalizers and filters for differential signals.

The MAX3885ECB and DG126 are commonly used in a variety of applications, including remote access units, high performance data centers, digital medical imaging, and enterprise storage networks. In addition, they can be used to provide I/O interface to system buses and backplanes, as well as router and switch ports. The serializer/deserializer also provides reliable high-speed communications in applications such as 3G/4G backhaul, test & measurement systems, video broadcast systems, etc.

The MAX3885ECB serializer/deserializer incorporates two main components - a linear deserializer and a deterministic equalizer. The linear deserializer receives and processes the differential receive data stream, providing the necessary signal conditioning and clock recovery functions to perform jitter attenuation. The equalizer uses a noise-predictive deterministic polynomial equalizer algorithm to compensate for signal modifications resulting from crosstalk and ISI. The equalizer also adjusts the transmit equalization settings in order to provide best-fit performance for a wide range of data rates and channel conditions. Furthermore, it is capable of measuring the quality of received signals, allowing for adjustments to the equalizer settings in order to achieve the optimal alignment and equalization strategies.

The DG126 is a component that performs equalization for differential transmit signals. It utilizes a double-driven equalizer that compensates for ISI caused by crosstalk coupled with an adaptive equalization algorithm to provide optimal transmit performance. The component also ensures that differential signals conform to the required eye pattern specification by providing accurate transition times and flat amplitude profiles. Additionally, the component offers jitter transfer functions and jitter attenuation characteristics needed to ensure proper operation at high data rates.

The MAX3885ECB+DG126 SERDES product offers sophisticated design techniques along with comprehensive performance data to enable systems to achieve maximum performance. As a member of the GDP family, it has the highest performance levels for both differential and common mode signal equalization, making it the ideal solution for high-speed serial interfaces. With optimized design algorithms and implementation techniques, the product provides reliable, high-performance links for remote access units, high performance data centers, digital medical imaging, enterprise storage networks, 3G/4G backhaul, test & measurement systems, video broadcast systems, and other applications.
