Introduction

The MAX3693ECJ+T, one of Maxim Integrated\'s Family of devices, is a universal serializer/deserializer (SERDES) offering more advanced and robust system design flexibility than traditional serializer/deserializer solutions. It operates as both a universal serializer/deserializer and a two-channel non-return-to-zero (NRZ). Within such a context, the MAX3693ECJ+T has numerous application fields that integrate with the system design and a detailed working principle.

Application Field

The MAX3693ECJ+T is designed for a wide range of applications. It is particularly suitable for applications such as digital video distribution, Print-on-Demand (PoD) systems, or in industrial sensing or measurement applications. In digital video distribution systems, the MAX3693ECJ+T offers support for resolutions up to 1080p/60Hz, allowing multiple digital video streams to be switched between several sources. In PoD systems, the MAX3693ECJ+T eliminates the need to design a board-level interface serially and supports 921.6Kbps clock rates.

The MAX3693ECJ+T also provides differential I/O that enables it to be used in measurement and industrial sensing applications, for accurate and reliable data transmission using NRZ modulation. The differential design minimizes noise, thereby improving signal integrity and enables the chip to cope with long cable runs without introducing high bit errors.

The chip also provides a built-in output current driver, allowing the differential output to be connected directly to a standard PCF connector without the need for an external driver. It also offers system design flexibility through its three supply voltages and pin-selectable serial clock rates.

Working Principle

The MAX3693ECJ+T is built on a 55-bit serial interface with an integrated deserializer, allowing a single channel to be used in both directions. Along with the 55-bit serial interface, the MAX3693ECJ+T also includes an embedded microcontroller which can be programmed to set up different serial clock frequencies, output data formats and supply voltage settings. The chip is also capable of operating in a NRZ mode, which is an ideal solution for applications that do not require a high data rate.

The MAX3693ECJ+T features selectable clock rates of 800Mb/s, 400Mb/s and 200Mb/s, and support for multiple video formats. The clock rates are selected via a pin-selectable option. Furthermore, the MAX3693ECJ+T integrates an on-chip Voltage Regulator (VRM) to supply the logic core and core drivers, as well as an on-chip Clock Reference Oscillator (CRO). This CRO can run at either 12.8GHz or 25.6GHz, depending on the application.

The MAX3693ECJ+T also incorporates a differential buffered signaling technique that allows the chip to operate at up to 18Gbps. This is accompanied by variable input equalization and cable equalization controls, allowing the system to adjust to a wide range of input load conditions.

The chip also features integrated output current drivers that can be used to directly interface with a standard PCF output connector. The integrated on-chip ESD diode and EMI filter ensures protection against electrostatic discharges and electromagnetic interference.

Conclusion

The Maxim Integrated MAX3693ECJ+T is a universal serializer/deserializer that can operate as a two-channel non-return-to-zero (NRZ). It offers support for resolutions up to 1080p/60Hz, 921.6Kbps clock rates, and built-in output current driver support. Its 55-bit serial interface with an integrated deserializer allows single channel use in both directions, along with pin-selectable serial clock rates. The chip is also capable of operating in NRZ mode, and features a Voltage Regulator (VRM) and Clock Reference Oscillator (CRO) to supply the logic core and core drivers. The MAX3693ECJ+T is an ideal solution for a variety of applications including digital video distribution, Print-on-Demand (PoD) systems, and industrial sensing or measurement applications.
