AD9863屬于RF/IF射頻/中頻RFID的射頻前端（LNA+PA）。由亞德諾半導體技術有限公司制造生產(chǎn)的AD9863射頻前端（LNA + PA）本系列中的產(chǎn)品是各種集成電路，其中集成了射頻 (RF) 信號鏈連接到系統(tǒng)天線的部分中常見的一種或多種功能，如低噪聲放大器 (LNA) 和可編程放大器 (PA)。任何給定器件所含的實際功能各不相同，相比旨在提供更高應用靈活性的器件，針對相對較窄應用的器件通常集成更大一部分必要的信號鏈。

GENERAL DESCRIPTION

The AD9863 is a member of the MxFE family—a group of integrated converters for the communications market. The AD9863 integrates dual 12-bit analog-to-digital converters (ADC) and dual 12-bit digital-to-analog converters (TxDAC?). The AD9863 ADCs are optimized for ADC sampling of 50 MSPS and less. The dual TxDACs operate at speeds up to 200 MHz and include a bypassable 2× or 4× interpolation filter.

FEATURES

Receive path includes dual 12-bit, 50 MSPS analog-to-digital converters with internal or external reference

Transmit path includes dual 12-bit, 200 MSPS digital-to-analog converters with 1×, 2×, or 4× interpolation and programmable gain control

Internal clock distribution block includes a programmable phase-locked loop and timing generation circuitry, allowing single-reference clock operation

24-pin flexible I/O data interface allows various interleaved or noninterleaved data transfers in half-duplex mode and interleaved data transfers in full-duplex mode

Configurable through register programmability or optionally limited programmability through mode pins

Independent Rx and Tx power-down control pins

64-lead LFCSP package (9 mm × 9 mm footprint)

APPLICATIONS
