Ripley GNSS Chipset

Ripley is a 3-channel high precision broadband GNSS chipset, with each separately configurable channel integrating an RF frontend, IF filter, automatic gain control and ADC. It can simultaneously receive multi-frequency signals from all constellations, with a sampling rate of up to 120 MHz.

The system is highly configurable, with programmable low-pass filter bandwidth from 4 to 40 MHz and either analogue or digital output. The 4 bit-ADC can utilize three common code types (SIG/MAG code, binary complement code and unsigned code), and also supports four-wire SPI with a maximum configuration rate of 10 MHz.
