Product Details

The MAX5862 evaluation kit (EV kit) contains two MAX5862 high-density downstream cable QAM modulators that each integrate a digital upconverter (DUC) and an RF digital-to-analog converter (RF-DAC). The device’s DUC performs QAM mapping, pulse shaping, and digital RF upconversion of FEC-encoded data with full agility and then drives a 14-bit, 4.6Gsps RF-DAC. Each device digitally synthesizes RF signals with up to 32 DOCSIS®-compliant 6MHz or 8MHz QAM channels on a single RF port at frequencies from 47MHz to 1006MHz.
The EV kit provides a complete two-port system solution for high-density QAM modulation with very low power dissipation.
The EV kit includes Windows XP®-, Windows Vista®-, and Windows 7-compatible software that provides a simple graphical user interface (GUI) for configuration of all of the MAX5862 registers, control of the SPI interface, temperature monitoring, and for control of the high-speed data converter evaluation platform (HSDCEP) board. Software to control the MAX5862 registers and SPI is also Windows 7 compatible.
The EV kit provides two QSH Samtec connectors to interface to the HSDCEP for driving the IC’s single input port and various control signals.

Applications

  • Edge QAM, CMTS, CCAP, IP-QAM
  • Multi-Dweller Unit Mini-Headends
  • Remote PHY, Coax Media Converters
