NXP Semiconductors SAA7826

the SAA732X design (the original features are maintained) • Software compatibility is maintained with the SAA732X by using a similar register structure (new features are controlled from new shadow registers) • 1×, 2× and 4× speed • LF (servo) signals converted to digital representations by 6 oversampling bitstream ADCs • HF part summed from signals D1 to D4 and converted to a digital signal by a data slicer • On-chip buffering and filtering of the diode signals from the mechanism for signal optimization • Selectable DC offset cancellation of quiescent mechanism voltages and dark currents •...
