GXSC Dual-Channel 10-Bit 1.0 GSPS High-Speed Analog-to-Digital Converter (ADC10D1000) for Broadband Communication Applications

The signal transmission bandwidth of broadband communication systems ranges from hundreds of megahertz to tens of gigahertz, requiring the processing of multi-carrier and highly modulated analog signals. This imposes far stricter demands on analog-to-digital converters (ADCs) than traditional communication scenarios, while also presenting numerous technical challenges. The primary requirements include an ultra-high sampling rate, necessitating an ADC with a sampling rate exceeding 1 GSPS. Additionally, the ADC must achieve high spurious-free dynamic range (SFDR) and high signal-to-noise ratio (SNR) to prevent interference from strong signals on weak signals.

The GXSC dual-channel 10-bit 1.0GSPS high-speed analog-to-digital converter is specifically designed for high-speed signal acquisition. Through innovative architecture design and process optimization, it adopts a proprietary architecture to achieve excellent dynamic performance with low power consumption below 2.3W, perfectly matching the core requirements of broadband communication. Each channel ADC features independent DDR data clocks (DCLKI and DCLKQ). When both channels of the ADC are operational, DCLKI and DCLKQ remain in phase, enabling the use of only one clock to sample all channels. The chip supports AutoSync automatic synchronization functionality, facilitating multi-chip cascading. It also supports automatic synchronization for multi-ADC cascading on a single board and multi-ADC cascading across multiple boards.

The data output format of the GXSC analog-to-digital converter can be programmed to either offset binary code format or two‘s complement binary format, allowing users to choose the preferred mode. The product utilizes a parallel LVDS interface for data output, with a minimum conversion delay of 26ns. The data interface supports both Demux mode and Non-Demux mode. In Demux mode, two sets of 10-bit LVDS buses output data in parallel, reducing the data rate of each LVDS bus by half to accommodate more data receiving devices.
