LM97593 is a digital downconverter with integrated 12-bit analog-to-digital converters (ADCs) and automatic gain control (AGC)
The LM97593 integrates two 12‑bit analog‑to‑digital converters, a digital downconverter, and an automatic gain control circuit in a single 128‑pin PQFP package. It supports direct IF sampling up to 300 MHz and provides both serial and parallel data interfaces, making it suitable for cellular base stations, satellite receivers, and other wireless communication systems.
Key features include 100 % software compatibility with the CLC5903, on‑chip precision reference, 123 dB dynamic range with a DVGA, and programmable FIR filters (21‑tap and 63‑tap). The device operates from standard 3.3 V analog and digital supplies and offers a range of power‑saving modes.
