OVFL - Overflow, Pin 2.

Overflow indicates analog input overrange, for both the Left and Right channels, since the last

update request on the PEAK UPDATE (PU) pin. A value of 1 in the register indicates an

overrange condition. The left channel information is output on OVFL during the left channel

portion of LRCK. The right channel information is available on OVFL during the right channel

portion of LRCK. The registers are updated with a high to low transition on the PEAK

UPDATE pin. A 47 kohm pull-down resistor on this pin will set the CS5334/5 in Master Mode.

FRAME - Frame Signal, Pin 10.

Frames the Peak Signal Level (PSL) Bits. FRAME goes high coincident with the leading edge

of the first PSL bit and falls coincident with the trailing edge of the last PSL bit as shown in

Figures 3-5. A 47 kohm pull-down resistor on this pin will set the Peak Signal Level

Monitoring format to "Bar Graph" mode.

PARAMETER DEFINITIONS

Dynamic Range

The ratio of the rms value of the signal to the rms sum of all other spectral components over

the specified bandwidth. Dynamic Range is a signal-to-noise ratio measurement over the

specified band width made with a -60dBFs signal. 60dB is added to resulting measurement to

refer the measurement to full-scale. This technique ensures that the distortion components are

below the noise level and do not effect the measurement. This measurement technique has been

accepted by the Audio Engineering Society, AES17-1991, and the Electronic Industries

Association of Japan, EIAJ CP-307. Expressed in decibels.

Total Harmonic Distortion + Noise (THD+N)

The ratio of the rms value of the signal to the rms sum of all other spectral components over

the specified band width (typically 10 Hz to 20 kHz), including distortion components.

Expressed in decibels. Measured at -1 and -20 dBFs as suggested in AES17-1991 Annex A.

Frequency Response

A measure of the amplitude response variation from 10 Hz to 20 kHz relative to the amplitude

response at 1 kHz. Units in decibels.

Interchannel Isolation

A measure of crosstalk between the left and right channels. Measured for each channel at the

converter’s output with no signal at the input under test and a full-scale signal applied to the

other channel. Units in decibels.

Interchannel Gain Mismatch

The gain difference between left and right channels. Units in decibels.

Gain Error

The deviation from the nominal full-scale analog input for a full-scale digital output.
