APPLICATIONS

  • MCNS/DOCSIS Compliant Cable Modems
  • CATV Interactive Set-Top Box
  • OpenCable Set-Top Box
  • Fiber Nodes
  • Cable Modem Termination Systems (CMTS) PRODUCT DESCRIPTION The ARA05050 is a GaAs IC designed to provide the reverse path amplification and output level control functions in a CATV Set-Top Box or Cable Modem. It incorporates a digitally controlled precision step attenuator that is preceded by an ultra low noise amplifier stage, and followed by an ultra-linear output driver amplifier. This device is capable of meeting the MCNS/DOCSIS requirements for harmonic Figure 1: Cable Modem or Set Top Box Application Diagram

ELECTRICAL CHARACTERISTICS

Table 2: Absolute Minimum and Maximum Ratings Table 3: Operating Ranges Stresses in excess of the absolute ratings may cause permanent damage. Functional operation is not implied under these conditions. Exposure to absolute ratings for extended periods of time may adversely affect reliability. The device may be operated safely over these conditions; however, parametric performance is guaranteed only over the conditions defined in the electrical specifications. Notes: 1. Pins 3 and 26 should be AC-coupled. No external DC bias should be applied. 2. Pins 10, 11, 24 and 25 should be grounded or pulled to ground through a resistor. No external DC bias should be applied. 3. Pins 6, 7, 8, 9, 20, 21, 22 and 23 should be AC-grounded. No external DC bias should be applied.
