1.4
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, see Table
6, and is high pass filtered to fall out of the pass band.
The frequency characteristics of the added dither is illustrated in Section 3.
1.5
Second order noise shaping can be applied to interpolated data prior to being passed to the DAC
core. When enabled this provides an additional reduction in quantisation noise to that gained through
the use of interpolation filtering. For the x4 interpolation mode this improvement will be 16dB,
equivalent to 2.7 bits.
1.6
The MB86060 interpolating DAC incorporates a number of novel design aspects that are subject to
patent applications. Key to its operation are the current sources where segmented, common centroid,
interleaved techniques for the most significant bits, as well as load matching ensure good linearity
and low distortion to at least the 12-bit level. In the switch elements tracking capacitance is minimised
to improve settling, while controlled rise and fall times improve SFDR performance. Finally the digital
decoding uses a 3-dimensional addressing approach to minimise propagation delays from latch to
element.
