AD8153ACPZ-RL7

Signal Switches, Multiplexers, Decoders Overview

The AD8153ACPZ-RL7 is a single-lane, asynchronous, protocol-agnostic 2:1 multiplexer and 1:2 demultiplexer switch manufactured by Analog Devices Inc. It operates with differential CML inputs and outputs, supporting data rates from DC to 3.2 Gbps. The device features two levels of input equalization and four levels of output pre-emphasis to compensate for channel loss. It includes on-chip terminations, loopback capabilities, and unicast/bicast functions. Powered by a 3.3 V core supply, it is housed in a 32-lead LFCSP package.

Signal Switches, Multiplexers, Decoders Feature Summary

• Supports 2:1 multiplexing and 1:2 demultiplexing with unicast or bicast routing options.
• Provides adaptive signal integrity through two levels of receive equalization and four levels of transmit pre-emphasis.
• Enables comprehensive testing via loopback functionality on all ports.
• Offers flexible control through pin mode, serial I2C interface, or mixed mode operation.

Signal Switches, Multiplexers, Decoders Applications

• Low cost redundancy switching
• SONET OC48/SDH16 and lower data rates

Signal Switches, Multiplexers, Decoders Procurement Notes

Verify the specific ordering suffix RL7 corresponds to the reel packaging configuration required for your assembly line. Confirm that the I2C address pins are set correctly for your system topology. Ensure the PCB design adheres to the thermal and impedance guidelines specified in the datasheet to maintain signal integrity at high speeds.

Signal Switches, Multiplexers, Decoders Selection Notes

Select this component for applications requiring a single-lane high-speed switch with integrated signal conditioning. It is suitable for systems needing redundancy or test loopback without external components. Consider the I2C interface if digital control of equalization and pre-emphasis is preferred over manual pin settings.

Signal Switches, Multiplexers, Decoders Part Context

This part belongs to the XStream™ family of high-speed switches from Analog Devices. It is designed for backplane and board-to-board interconnects where signal degradation is a concern. The device complements other members like the AD8159 for multi-lane applications.

Signal Switches, Multiplexers, Decoders FAQ

What are the three operating modes of the AD8153?

The AD8153 supports pin mode, serial mode, and mixed mode. Pin mode uses external pins for all controls. Serial mode uses an I2C interface for all controls. Mixed mode allows lane switching via pins while using I2C for advanced features like equalization.

How does the AD8153 handle signal degradation in long traces?

It compensates for signal degradation using two levels of input equalization (receive EQ) and four levels of output pre-emphasis (transmit PE), which can be configured per port via pins or I2C registers.
