Video Amps And Modules datasheet and documents for MAX2557AELM+T
Video Amps And Modules Overview
The MAX2557AELM+T is a direct-conversion, RF-to-bits wireless receiver designed for HSPA-FDD femto base stations. It integrates four LNAs with internal 50Ω matching, quadrature mixers, baseband anti-aliasing filters, programmable gain amplifiers, and a high-dynamic-range continuous-time Sigma-Delta ADC. The device includes an on-chip fractional-N frequency synthesizer for LO and sampling clock generation. It outputs a 1-bit digital I/Q stream via a programmable LVDS-like interface, enabling digital channel filtering in the baseband DSP.
