CXD2755Q

Super Audio CD Format Book ANNEX D&E Conformal Metering

Description

208 pin QFP (Plastic)

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 the signal level measurement and

display.

Structure

Silicon gate CMOS IC

Functions

• Up to 8 channels of 1bit, 2.8224MHz (44.1kHz × 64)

DSD input supported.

Absolute Maximum Ratings (Ta = 25°C)

• Supply voltage

• Input voltage

• Output voltage

V^DD

VSS – 0.5 to + 4.6

• MaxPeak measurement (ANNEX D3):

28-tap 1st-order moving average filter is used for

MaxPeak level measurement.

VSS – 0.5 to VDD + 0.5

VO VSS – 0.5 to VDD + 0.5

• Storage temperature

Tstg

• DC removal filter:

–55 to +150

°C

DC removal filter (fc = about 0.1Hz) is inserted to

HF/MF/LF filters.

Recommended Operating Conditions

• HF measurement (ANNEX D4):

40kHz 5th-order Butterworth high-pass filter and

100kHz 5th-order Butterworth low-pass filter are

used for HF band measurement. In addition,

"Mean-Square" and "Square-Root" are calculated

for RMS metering.

• Supply voltage

V^DD

3.0 to 3.6

• Operating temperature

Topr

–10 to +75

°C

Input/Output Capacitance

• Input capacitance

• Output capacitance

Max. 9pF

• 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.

Max. 11pF

Note) Measurement conditions

VDD = VI = 0V, fM = 1MHz

• 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.
