4 GHz Clock Reference Design for 12 Bit High Speed ADCs in Digital Oscilloscopes & Wireless Testers
Description
The TIDA-01015 is a clocking solution reference design for high speed direct RF sampling GSPS ADCs. This design showcases the significance of the sampling clock to achieve high SNR for 2nd Nyquist zone input signal frequencies. ADC12J4000 is a 12-bit: 4-GSPS RF sampling ADC with 3-dB input bandwidth of 3.2 GHz capable of capturing signals up to 4 GHz. This design highlights a clocking solution for the ADC12J4000 using TRF3765: to achieve high SNR performance at high input frequencies used in applications such as digital storage oscilloscopes (DSO) and wireless testers.
