Description

TIDA-01016 is a clocking solution for high dynamic range high speed ADC. RF input signals are directly captured using the RF sampling approach by high speed ADC. The ADC32RF45 is a dual- channel, 14-bit, 3-GSPS RF sampling ADC. The 3-dB input bandwidth is 3.2 GHz, and it captures signals up to 4 GHz. This design showcases the clocking solution using the LMX2582, to achieve the best SNR performance of ADC32RF45 at higher input frequencies used in microwave backhaul applications.

Features
  • 3 GHz low-phase noise clocking solution for RF sampling ADC with >51 dB SNR @ 3.65 GHz input
  • 4GHz high frequency input signal capture capability
  • Large signal bandwidth, high dynamic range RF sampling receiver solution
