25 Gbps Compensates 40 inches of FR4 at 4.
25 Gbps Low power: 130 mW per channel at 3.
3 V (outputs enabled) 16 × 16, fully differential, nonblocking array Double rank connection programming with dual connection maps 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 Serial (I2C slave or SPI) control interface 100-lead TQFP, Pb-free package APPLICATIONS Fiber optic network switching High speed serial backplane routing to OC-48 with FEC XAUI: 10GBASE-KX4 Gigabit Ethernet over backplane: 1000BASE-KX 1×, 2×, and 4× Fibre Channel InfiniBand® Digital video (HDMI, DVI, DisplayPort, 3G-/HD-/SD-SDI) Data storage networks GENERAL DESCRIPTION The ADN4604 is a 16 × 16 asynchronous, protocol agnostic, digital crosspoint switch, with 16 differential PECL-/CMLcompatible 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.
