The ADN2855ACPZ is a highly-integrated integrated multirate clock and data recovery chip designed for use in the reconfigurable optical networks, radio systems, and other telecommunications applications. It is a general-purpose chip designed for use in applications ranging from base stations to network access nodes. The main feature of the chip is that it can be used both as a conventional clock and data recovery (CDR) device, or as an optical transponder/repeater that integrates multiple functions. The ADN2855ACPZ also has programmable clock/data synthesis/generation capabilities, which make it suitable for applications in a variety of areas.

The ADN2855ACPZ combines two key technologies: integrated multi-rate clock and data recovery, and programmable clock/data synthesis/generation. Its clock and data recovery integrated architecture is based on high-performance low-power analog/digital circuitry combined with an advanced clock synthesis circuit. This chip’s high-performance, low-power design makes it suitable for operation in both moderate- and large-scale optoelectronic environments.

The ADN2855ACPZ has user-programmable clock synthesis/generation capabilities to meet the needs of various applications. The device features OTP (On-the-fly) Pre-Scaling and Residual time-to-Digital-Core (DTC) Calibration. It can also be used to generate advance warning signals, such as pre-warning signals and/or early-warning signals. This feature is useful when operating in high-delay networks. It can also be used to generate clock-to-data ratio (CDR) and clock ratio (CR) control signals, which are used in SDH/SONET receivers and transmitters. The chip also includes a programmable data input/output interface, which allows it to be interfaced with peripherals and other devices.

The ADN2855ACPZ can be used in both a conventional clock and data recovery environment, or as an optical transponder/repeater. In a conventional CDR environment, the chip serves as a clock synthesis/generation device and is used to recover digital bitstreams from multiple sources. It can also be programmed to generate master clock signals for other devices. In an optical transponder/repeater environment, the chip serves as an optoelectronic transponder/repeater and is used to convert optical signals from one protocol to another.

The ADN2855ACPZ is suitable for use in a variety of applications, such as telecommunications, wireless radio systems, and reconfigurable optical networks. It is a flexible solution for integrated clock and data recovery applications, and can be used both as a conventional CDR or as an optical transponder/repeater. Its programmable clock synthesis/generation capabilities make it an ideal choice for a variety of clock generation applications. Its advanced OTP pre-scaling and time-to-digital-core calibration capabilities make it a strong choice for applications in telecommunications and broadcast systems.
