Introduction

The AD6636 is a digital downconverter intended for IF sampling or oversampled baseband radios requiring wide bandwidth input signals. The AD6636 has been optimized for the demanding filtering requirements of wideband standards, such as CDMA2000, UMTS, and TD - SCDMA, but is flexible enough to support wider standards such as WiMAX. The AD6636 is designed for radio systems that use either an IF sampling ADC or a baseband sampling ADC.

Features

• 4/6 independent wideband processing channels
• Processes 6 wideband carriers (UMTS, CDMA2000)
• 4 single - ended or 2 LVDS parallel input ports (16 linear bit plus 3 - bit exponent) running at 150 MHz
• Supports 300 MSPS input using external interface logic
• Three 16 - bit parallel output ports operating up to 200 MHz
• Real or complex input ports
• Quadrature correction and dc correction for complex inputs
• Supports output rate up to 34 MSPS per channel
• RMS/peak power monitoring of input ports
• Programmable attenuator control for external gain ranging
• 3 programmable coefficient FIR filters per channel
• 2 decimating half - band filters per channel
• 6 programmable digital AGC loops with 96 dB range
• Synchronous serial I/O operation (SPI, SPORT - compatible)
• Supports 8 - bit or 16 - bit microport modes
• 3.3 V I/O, 1.8 V CMOS core
• User - configurable, built - in, self - test (BIST) capability
• JTAG boundary scan

Applications

• Multicarrier, multimode digital receivers
