MAX5882 - 4.6Gsps Cable Downstream Direct RF Synthesis DAC

General Description

The MAX5882 14-bit, 4.6Gsps digital-to-analog converter (DAC) is designed for direct RF synthesis of multicarrier quadrature amplitude modulation (QAM) signals in cable modem termination systems (CMTS) and edge QAM (EQAM) devices.

Key Features

  • excellent spurious, noise, and adjacent-channel power (ACP) performance, and directly synthesizes multiple carriers in the 47MHz to 1003MHz cable downstream band, as defined by the Data-Over-Cable Service Interface Specification (.

EVALUATION KIT AVAILABLE MAX5882 14-Bit, 4.6Gsps Cable Downstream Direct RF Synthesis DAC General Description The MAX5882 14-bit, 4.6Gsps digital-to-analog converter (DAC) is designed for direct RF synthesis of multicarrier quadrature amplitude modulation (QAM) signals in cable modem termination systems (CMTS) and edge QAM (EQAM) devices. The DAC features excellent spurious, noise, and adjacent-channel power (ACP) performance, and directly synthesizes multiple carriers in the 47MHz to 1003MHz cable downstream band, as defined by the Data-Over-Cable Service Interface Specification (DOCSISM). The 4.6Gsps update rate allows digital generation of signals with more than 2GHz bandwidth.
