Description

CE5038 is a fully integrated tuner for advanced modulation satellite receivers, operating over 950 - 2150 MHz and symbol rates in the range 1 - 45 MS/s.

It contains a selectable RF bypass for connecting to a second receiver module. CE5038 simply requires a crystal reference and operates from a 5 V supply. It is designed as a simple to use stand-alone tuner, requiring no training algorithms or user/demodulator intervention to optimize performance.

The CE5038 can be used with an advanced modulation demodulator to create a highly-integrated front-end solution, operating from 1-45 MS/s.
