Equalizer IC eases DOCSIS 4.0 CATV upgrades


A single-chip inverse cable equalizer, the QPC7330 from Qorvo permits CATV operators to improve their hybrid fiber coax (HFC) networks to DOCSIS 4.0. The QPC7330 streamlines area set up by eliminating the necessity for plug-ins or sophisticated circuitry to implement the enter cable simulation operate. Programmed via an I2C interface, the gadget seamlessly integrates into the automated setup routine.

The operate of the QPC7330 75-Ω inverse cable equalizer is to flatten out an enter sign with an excessive amount of uptilt in a line extender or system amplifier. It options 25 states to simulate the lack of completely different lengths of coaxial cable, providing tilt changes from 1 dB to 24 dB (measured from 108 MHz to 1794 MHz). The gadget integrates all equalizer capabilities, together with a low-loss bypass mode, into a ten×14-mm laminate over-mold module.

The QPC7330 inverse cable equalizer is sampling now, with manufacturing portions accessible in August 2024.
