1 A −1.0 dBFS input level at the analog inputs corresponds to an output level of −2.5 dBFS when using the fixed-frequency NCO and 95 MHz FIR filter. When using the

tunable-frequency NCO and 100 MHz FIR filter, the output level is −1.3 dBFS. These respective output level reductions are due to FIR filter losses. See the

section for more details.
