X-STREAM™ 4.25 Gbps, 16 × 16, Digital Crosspoint Switch

Viewing:

Overview

  • DC to 4.25 Gbps per port NRZ data rate
  • Programmable receive equalization
  • Programmable transmit preemphasis/deemphasis
  • Low power: 130 mW per channel at 3.3 V (outputs enabled)
  • 16 × 16, fully differential, nonblocking array
  • Low jitter, typically 20 ps
  • Flexible I/O supply range
  • DC- or ac-coupled differential CML inputs
  • Programmable CML output levels
  • Per-lane input P/N pair inversion for routing ease
  • 50 Ω on-chip I/O termination
  • Supports 8b/10b, scrambled or uncoded NRZ data
  • See data sheet for additional Features

The ADN4604 is a 16 × 16 asynchronous, protocol agnostic, digital crosspoint switch, with 16 differential PECL-/CML-compatible inputs and 16 differential CML outputs.

The ADN4604 is optimized for nonreturn-to-zero (NRZ) signaling with data rates of up to 4.25 Gbps per port. Each port offers a fixed level of input equalization and programmable output swing and output preemphasis.

The ADN4604 nonblocking switch core implements a 16 × 16 crossbar and supports independent channel switching through the serial control interface. The ADN4604 has low latency and very low channel-to-channel skew.

An I2C® or SPI interface is used to control the device and provide access to advanced features, such as additional levels of preemphasis and output disable.

The ADN4604 is packaged in a 100-lead TQFP package and operates from −40°C to +85°C.
