1. Board Overview
This daughter card is a FMC board for the high speed AD9152 DAC and AD9680 ADC. It provides customers with up to 2GHz of usable analog bandwidth and a JESD204B interface to quickly prototype a variety of wideband RF applications.
Includes 1 AD chip AD9680, on-chip dual-channel, 14-bit, 1GSPS analog-to-digital conversion. This analog-to-digital converter can achieve 80dBc spurious-free dynamic range (SFDR) performance and 61.4dBFS signal-to-noise ratio (SNR) when converting 1GHz input, while the total power consumption per channel is 1.65W. The DAC in the kit is a dual-channel, 16-bit, 2.25GSPS AD9152, with an SFDR of 82 dBc and a maximum sampling rate of 2.25GSPS, which can generate multi-carriers up to the Nyquist frequency. AD9528, a low-jitter clock generator provides low-power, multi-output clock distribution functions with low jitter performance, and is also equipped with an on-chip PLL, VCO and two VCO dividers.
2. Performance indicators
- FMC interface, supports 2-way AD input and 2-way DA output.
- Two-way AD, AD uses the AD9680 chip, which integrates two 14-bit high-speed ADCs with a sampling rate of up to 1GSPS and a physical interface of SMA.
- Two-way DA, DA uses AD9152 chip, which has 16-bit resolution, maximum input data rate of 2.25Gsps, 50 ohm impedance, and physical interface of SSMB.
- The clock uses a temperature compensated crystal oscillator 256.25MHZ, 1ppM, and the chip is AD9528.
- Support external clock input, access the clock chip through the SMA interface, and input the frequency multiplication to the AD and DA chips.
- The size of the FMC card is 69mm x 90mm. The size of the mounting hole is 2.7mm.
