... Incorporated into the PCM1702 is an advanced sign magnitude architecture that elimi- nates unwanted glitches and other nonlinearities around bipolar zero. The PCM1702 also features a very low noise (120dB typ SNR: A-weighted method) and fast settling current output (200ns typ, 1.2mA step) which is capable of 16X oversampling rates ...

... See the “–90dB Signal Spectrum” plot in the Typical Perfor- mance Curves section for the power spectrum of a PCM1702 at a –90dB output level. (The “–90dB Signal” plot shows the actual –90dB output of the DAC). The deviation from ideal for PCM1702 at this signal level is typically less than 0.3dB. For the “ ...

... Latch Enable. Refer to Figure 2 for graphical relationships of these signals. Maximum Clock Rate A typical clock rate of 16.9MHz for the PCM1702 is derived by multiplying the standard audio sample rate of 44.1kHz by sixteen times (16X over-sampling) the standard audio word bit length of 24 bits (44.1kHz 16.9MHz). Note that this clock rate accommodates a 24-bit word length, even though only 20 bits are actually being used ...
