The CXD2755Q is the signal processor for signal level measurement of DSD (Direct Stream Digital) conformed to ANNEX D&E of Super Audio CD Format Book V1.2. This LSI can measure up to 8 channel DSD signals to detect the maximum level of each frequency band specified in ANNEX D&E of Super Audio CD format and output the peak values of every 44.1kHz cycle for th.
MF measurement (ANNEX E2): 20kHz 10th-order Butterworth high-pass filter and 50kHz 5th-order Butterworth low-pass filter are used for MF band measurement.
• LF measurement: 20kHz 10th-order Butterworth low-pass filter is used for LF band measurement.
• DC measurement (ANNEX E4): 0.1Hz 2nd-order low-pass filter is used for DC measurement.
• MF over warning flag (ANNEX E2): As the MF specification has the exceptional condition for warning, the signal level of MF and LF are continuously compared and output the warning status from this LSI. 208 pin QFP (Plastic)
