AFE4900YZR

The AFE4900YZR is a high-performance, multichannel, digital down-converter (DDC) from Texas Instruments (TI). It is designed for use in a variety of applications, including software-defined radios (SDRs), wireless infrastructure, and test and measurement equipment.

Description:

The AFE4900YZR is a highly integrated DDC that offers high performance and flexibility for a wide range of applications. It features a dual 2x interpolation polyphase filter (PPF) and a dual 2x decimation PPF, which provide high spurious-free dynamic range (SFDR) and low noise figure (NF). The device also includes a digital signal processor (DSP) that can be used for filtering, gain control, and other signal processing functions.

Features:

• Dual 2x interpolation PPF and dual 2x decimation PPF for high SFDR and low NF
• Integrated DSP for filtering, gain control, and other signal processing functions
• Multichannel operation with up to 8 channels
• Wide input frequency range (20 MHz to 6 GHz)
• Low power consumption (less than 1 W)
• Small form factor (10x10 mm package)
• Industrial temperature range (-40°C to +85°C)
