Overview
The ADN4612ACPZ is a 12 × 12 asynchronous, protocol-agnostic digital crosspoint switch produced by Analog Devices Inc. This component is designed to handle high-speed data transmission with differential PECL-/CML-compatible inputs and differential CML outputs. It is optimized for nonreturn-to-zero (NRZ) signaling and supports data rates up to 11.3 Gbps per port. The ADN4612 features low latency, very low channel-to-channel skew, and is packaged in an 88-lead Lead Frame Chip Scale Package (LFCSP), operating over a temperature range of −40°C to +85°C.
