Replacing the ADC10D1500 with the GX10D1500 Dual-Channel 10-Bit 1.5GSPS ADC for Electronic Countermeasures

Electronic countermeasure reconnaissance uses electronic technology and electromagnetic wave technology, including radar countermeasures, radio communication countermeasures, and optoelectronic countermeasures. The system receives RF electromagnetic signals through antennas. After RF front-end filtering, low-noise amplification, and mixing down-conversion, the high-frequency wideband RF signal is converted into an intermediate-frequency analog signal, and high-speed ADCs complete instantaneous, continuous, wideband digital sampling.

Electronic countermeasure reconnaissance systems generally require ultra-wideband signal acquisition and high-dynamic-range anti-interference capability. The GX10D1500 dual-channel 10-bit 1.5GSPS analog-to-digital converter is very suitable for data acquisition in electronic countermeasure systems. The GX10D1500 can replace the ADC10D1500 pin to pin, featuring large input bandwidth, high sampling rate, good linearity, a small package, and low power consumption. Its power consumption is about 56% of that of the ADC10D1500, and it does not require a heat sink.

The GX10D1500 adopts an independently designed architecture and achieves excellent dynamic performance with low power consumption of less than 2.3W. Each channel ADC has an independent DDR data clock (DCLKI and DCLKQ). When both ADC channels are operating, DCLKI and DCLKQ are always in phase, so only one of them can be used to acquire all channels. It supports the AutoSync automatic synchronization function, which can be used for cascading multiple chips. It supports automatic synchronization for cascading multiple ADCs on a single board and for cascading multiple ADCs across multiple boards.
