Welcome Here  Shenzhen Mingjiada Electronics Co., Ltd.

Overview:

The ADC31RF80IRMP is a 14-bit 3GSPS RF sampling broadband receiver and feedback integrated circuit with input frequencies up to 4GHz and above. The ADC31RF80 is designed for a high signal-to-noise ratio (SNR) and provides noise spectral density of -155dBFS/Hz over a large input frequency range as well as dynamic range. Buffered analog inputs with on-chip terminals provide uniform input impedance over the entire wide frequency range and minimize sampling and retention of burr pulse energy. The device contains a dual-band digital downconverter (DDC) with up to three independent 16-bit numerical control oscillators (NCO) per DDC for phase-coherent hopping. Supports JESD204B serial interface with deterministic latency based on subclass 1, using data rates up to 12.5Gbps with up to 4 channels. The ADC31RF80 has an industrial temperature range of -40 °C to +85°C.
