FMC-ADC500-5, ADC 500MS/s 16bits

 

FMC-ADC500-5 is a High Pin Count (HPC) FMC module with 5 ADC channels, each channel running up to 500MS/s with a dynamic range of 16 bits. The module has 5 ADC31JB68 ICs from Texas Instruments in total with an HMC7044 from ADI, which is the source of clocks feeding the ADCs. We provide the provision for external clock input for this hardware.

An internal VCXO and TCXO clock are the input to HMC7044 with five clock outputs to the ADCs. HMC7044 offers an SYSREF clock with a known and adjustable delay, which can be sent to the FPGA as REF CLK and SYSREF CLK to achieve the requirement of subclass 1 JESD204B. The external clock input can be used as a Device clock for ADCs or as a reference clock.

ADC input signal bandwidth is 4.5 to 250MHz, while the external clock bandwidth is 10 to 800Mhz when used as a reference clock, and 400 to 4000Mhz when used as a device clock. Trigger maximum voltage will be 6V on this module.

External trigger input allows the addition of timestamps to the sample stream from ADCs. CLK IN can be a Sample clock input up to 4GHz or reference clock input up to 800MHz. Board clocking structure provides the possibility of deterministic latency and subclass one synchronization between multiple ADCs.
