Analog Devices AD1893 SamplePort Datasheet Rev A
The AD1893 SamplePort is a fully digital, stereo asynchronous sample‑rate converter designed for low‑cost, low‑power audio applications. It automatically senses input and output sample frequencies, rejects jitter, and supports dynamic clock tracking with slow‑ and fast‑settling modes.
The document provides detailed specifications, pin configurations, digital timing parameters, power consumption data, and theory of operation for designers and engineers.
