Ripley

GNSS RFIC

Ripley is a highly integrated 3-channel high precision broadband GNSS RFIC, each channel integrates RF front-end, IF filter, AGC and AD converter. Ripley can simultaneously receive BDS/GPS/GLONASS/GALILEO all-system multi-frequency signals. Its sampling rate can reach up to 120 MHz, with filter bandwidth configurable from 4 MHz to 40 MHz. The full-chip working current is 80 mA.

Highly Integrated 3-Channel Multi-Mode And Multi-Frequency GNSS RFIC

Features

Highly integrated 3-channel multi-mode multi-frequency GNSS RFIC.

Each channel can be separately configured to receive satellite navigation signals from 1.1GHz to 1.7GHz, within which any frequency/bandwidth is configurable.

Integrated programmable low-pass filter, support 4M, 10M, 20M, 32M, 40MHz and other bandwidth configurations. Support analog IF output and digital IF output.

Integrate 4 bit-ADC to support 3 common code types: SIG/MAG code, binary complement code and unsigned code, and support four-wire SPI with a maximum configuration rate of 10 MHz.

The working temperature range is -55~125℃.

QFN56 7mm×7mm×0.75mm package.
