ISLA214P50-55210EV1Z Daughter Board

Ultra High Performance Broadband 12 to 16-Bit Data Acquisition Platform


This ISLA214P50-55210EV1Z is an evaluation platform featuring Intersil's ultra-high dynamic range fully differential amplifier (FDA), the ISL55210, and the high speed, high performance, 14-bit, 500MSPS ADC, the ISLA214P50. In the delivered configuration, it offers a full signal path reference design providing a 100MHz flat channel bandwidth that achieves typically <-85dBc distortion terms with -2dBFS at the ADC inputs from a -7dBm single-ended input. The channel characteristics (pass band location, stop-band attenuation, gain, etc.), can be easily altered to suit your needs by modifying the 3rd order RLC filter between the amplifier and analog-to-digital converter. To facilitate immediate performance measurement and analysis, this PCB daughterboard mates to Intersil's existing high speed ADC evaluation platform.
