Analog Interface (Optional)

The Pico E‐14 also comes equipped with two high‐speed analog converters each capable of 14‐bit resolution. By default, both analog converters are powered down until the sleep lines are driven low and the amplifier lines are driven high by the FPGA. Both converters are capacitively coupled with pull‐ down resistors on the output to filter out any DC signal components. Both amplifiers are configured for minimum noise and unity gain.

The ADC is configured to utilize the internal 1.0V reference voltage and maximum full scale input, giving it a 2V pk‐pk input. Currently, the ADC is setup to accept input voltages between 0V and 2V. Clock modes and input data format is set by the system utilizing configuration pins available to the FPGA.

8‐Bit, 165 MSPS Digital‐to‐Analog Converter (DAC)*

The DAC is configured to utilize the internal 1.2V reference voltage and maximum full‐scale output, giving it a 2V pk‐pk output. Since the DAC actually outputs complementary currents, the amplifier is also utilized as a current to voltage converter and voltage shifter. This allows the voltage to be buffered within the 0V to 3V rail voltages. Currently, the DAC is setup to output between .5V and 2.5V. This gives us a comfortable .5V between our maximum outputs and rail voltages. Clock modes and input data format is set by the system utilizing configuration pins available to the FPGA.
