Description

The ADN4605ABPZ model is a digital crosspoint switch used for signal switching. It has a 40 × 40 asynchronous, protocol agnostic construction, which is compatible with 40 differential PECL/CML inputs and 40 differential programmable CML outputs.

Specifications and features

• DC to 4.25 Gbps per port NRZ data rate
• Adjustable receive equalization 3 dB, 6 dB, or 12 dB boost with compensates over 40 inches of FR4 at 4.25 Gbps
• Adjustable transmit preemphasis/deemphasis with programmable boost and output level that compensates over 40 inches of FR4 at 4.25 Gbps
• Low power 105 mW per channel at 2.5 V (400 mV p-p differential output level swing)
• 40 × 40, fully differential, nonblocking array with double rank connection programming with dual maps
• Low jitter, typically <25 ps
• Flexible 2.5 V to 3.3 V supply range
• DC- or ac-coupled differential PECL/CML inputs with differential CML outputs
• Per-lane polarity inversion for routing ease
• 50 Ω on-chip I/O termination with disable feature
• Supports 8b10b, scrambled or uncoded NRZ data with serial (IC slave or SPI) control interface and parallel control interface

Application Scenarios

• Digital video (HDMI, DVI, DisplayPort, 3G/HD/SD-SDI) applications
• Fiber optic network switching applications
• High speed serial backplane routing to OC-48 with FEC
• XAUI, 4x Fibre Channel, Infiniband®, and GbE over backplane applications
• Data storage networks

Comparison

• Flexible 2.5V to 3.3V supply range provides convenience for use in various applications
• Per-lane polarity inversion enables easy routing
• Nonblocking architecture with double rank connection programming allows for large-scale switching operations with multiple inputs and outputs

• May not be suitable for applications that require higher data rates than 4.25 Gbps per port NRZ
• Needs highly skilled personnel to operate
