ADC GX9215 Replaces AD9215 for Wired/Wireless Broadband Communication Applications

General wired/wireless communication systems need to process a large number of signals, which requires the use of ADC chips to convert the received analog RF signals into digital IF signals for subsequent digital signal processing, such as filtering and demodulation. Through the ADC‘s high-precision sampling and conversion of the signal, the device can more accurately recover the original signal, improve the performance and capacity of the communication system, and support more users to carry out high-speed data transmission at the same time.

The GX9215 is designed to digitize high-frequency, wide dynamic range signals and is ideally suited for demanding imaging and communications applications. With a sampling rate of up to 105MSPS and 10-bit precision, the GX9215 accurately converts analog signals to digital signals, providing high-quality data for subsequent digital signal processing. It has a 62dB signal-to-noise ratio and 72dB spurious-free dynamic range at 105MHz sampling. DC specifications include ±0.8LSB INL (typical), ±0.25LSB DNL (typical) and no leakage codes. Reference noise at the input is very low at 0.4LSB RMS.

The GX9215 is a single-channel, multi-stage differential pipeline architecture with built-in high-performance sample-and-hold circuitry and an on-chip reference voltage source. The GX9215 is supplied from a 3V analog power supply, and a single output power supply is capable of driving 2.1V to 3.6V logic circuits.

GX9215 Specifications:

- Flexible input range: 1VP-P to 2VP-P.

- Reference noise at input: 0.4LSBRMS

- On-chip reference voltage source and sample-and-hold circuitry

- Package Type: QFN-32

Wired/wireless broadband often requires processing signals from multiple channels, and the GX9215‘s multiplexing capability makes it suitable for multi-channel systems. It can quickly switch between different channels and sample them, realizing simultaneous processing of multiple user signals, improving the capacity and spectral efficiency of the base station, and meeting the needs of a large number of users communicating at the same time.
