Programmable Dither
Dither can be added to improve low-level performance and reduce effects due to nonlinearities within the
DAC, and reducing DNL and glitch energy. The dither has programmable amplitude, and is high pass
filtered to fall out of the pass band.
For dither to be used effectively both amplitude and frequency characteristics must be carefully considered.
Obviously the dither amplitude should be larger than the nonlinearities to be masked, but levels significantly
larger than this will ultimately limit available dynamic range for the wanted signal. Similar considerations
should be made for the frequency characteristics, which in the MB86060 the dither is highpass filtered such
that the majority of the energy is concentrated at Nyquist of the DAC output rate.
Development Kit
A development kit, reference DK86060, is available for the MB86060 16-bit Interpolating DAC. The kit
includes an evaluation board that enables simple and effective evaluation of the device.
The board provides a complete evaluation environment for the DAC. A transformer coupled differential
output interface is provided to simplify integration into
target applications and development environments. An
RF clock source can be connected via the transformer
coupled input, and 16-bit data via a 40-way IDC header.
The development kit includes,
