The ADN4605 4.25 Gbps 40 × 40 Digital Crosspoint Switch is a low power, high performance digital crosspoint switch supporting 4.25 Gbps NRZ data rate. It features adjustable receive equalization, adjustable transmit preemphasis/deemphasis, low jitter, programmable gain and output level, and a 40 × 40 fully differential, nonblocking array.
The ADN4605 digital crosspoint switch provides a fully differential 40 × 40 non‑blocking matrix with 40 PECL/CML‑compatible inputs and 40 programmable CML outputs. It is optimized for NRZ signaling and can operate at data rates up to 4.25 Gbps per port, offering adjustable input equalization and output pre‑emphasis.
The device is supplied in a 35 mm × 35 mm 352‑ball BGA package, operates from 2.5 V to 3.3 V, and is rated for temperatures from –40 °C to +85 °C. Control interfaces include I²C, SPI, and parallel modes, with detailed timing specifications provided for each.
