Product Details

The AD6674 is a 385 MHz bandwidth mixed-signal intermediate frequency (IF) receiver. It consists of two, 14-bit 1.0 GSPS/750 MSPS/500 MSPS analog-to-digital converters (ADC) and various digital signal processing blocks consisting of four wideband DDCs, an NSR, and VDR monitoring. It has an on-chip buffer and a sample-and-hold circuit designed for low power, small size, and ease of use. This product is designed to support communications applications capable of sampling wide bandwidth analog signals of up to 2 GHz. The AD6674 is optimized for wide input bandwidth, high sampling rate, excellent linearity, and low power in a small package.

The dual ADC cores feature a multistage, differential pipelined architecture with integrated output error correction logic. Each ADC features wide bandwidth inputs supporting a variety of user-selectable input ranges. An integrated voltage reference eases design considerations.

Applications

  • Diversity multiband, multimode digital receivers 3G/4G, TD-SCDMA, W-CDMA, GSM, LTE, LTE-A
  • DOCSIS 3.0 CMTS upstream receive paths
  • HFC digital reverse path receivers
