TAT2814A - DOCSIS 3.0 / Edge QAM Variable Gain Amplifier

Datasheet Summary

Description

The TAT2814A is an RFIC for DOCSIS 3.0 Output Sections, such as CMTS and Edge QAM.

It combines a low-reflection differential input stage, a variable gain step attenuator and an efficient output amplifier to provide significant reduction in power consumption and PC board space.

Features

  • Meets DOCSIS 3.0 with +4 dB typical performance margin < 5 Watt nominal power consumption Low-reflection differential input/output stages 18 dB typical return loss across entire gain range Variable gain attenuator: 18 dB typical range 30 dB typical max gain +49 dBm typical OIP3 2.7 dB typical noise figure Typical Input stage bias: 5 V, 290 mA Typical Output stage bias: 8 V, 415 mA 48-pin 7x7mm QFN laminate package.
  • General.
