Description
The CS5333 is a highly integrated, 24-bit, 96 kHz audio
ADC providing stereo analog-to-digital converters using
delta-sigma conversion techniques. This device includes
line level inputs in a 16-pin TSSOP package.
The CS5333 is based on delta-sigma modulation allow-
ing infinite adjustment of the sample rate between 2 kHz
and 100 kHz simply by changing the master clock
frequency.
The CS5333 operates from a +1.8 V to +3.3 V supply.
These features are ideal for set-top boxes, A/V receiv-
ers, DVD-karaoke players or any system which requires
optimal performance in a minimum of space.

ANALOG CHARACTERISTICS
(Continued)
Notes: 2. Filter response is guaranteed by design.
3. Filter characteristics scale with output sample rate. For output sample rates, Fs, other than 48 kHz, the
0.01 dB passband edge is 0.4535x Fs and the stopband edge is 0.625x Fs.
4. The analog modulator samples the input at 6.144 MHz for an Fs equal to 48 kHz. There is no rejection
of input signals which are multiples of the sampling frequency (n x 6.144 MHz 21.8 kHz where
n = 0,1,2,3...).
5. Group delay for Fs = 48 kHz, t
gd
= 15/48 kHz = 312 s.

Table 1. Common Clock Frequencies
Interface Power
1
VL (
Input) - Digital interface power supply. Typically 1.8 to 3.3 VDC.
Master Clock
2
MCLK (
Input) - The master clock frequency must be either 256x, 384x, 512x, 768x or
1024x the input sample rate in Base Rate Mode (BRM) and 128x, 192x, 256x, 384x the
input sample rate in High Rate Mode (HRM). Table 1 illustrates several standard audio
sample rates and the required master clock frequencies.
Serial Clock
3
SCLK (
Input/Output) - Clocks the individual bits of the serial data out of the SDOUT pin.
The required relationship between the Left/Right clock, serial clock and serial data is
defined by the DIF pin.
Serial Audio Data
Out (M/S select)
4
SDATA (
Output) - This pin serves two functions.
First: two's complement MSB-first serial data is output on this pin. The data is clocked out
of SDOUT via the serial clock and the channel is determined by the Left/Right clock. The
required relationship between the Left/Right clock, serial clock and serial data is defined
by the DIF pin.
Second: Master/Slave mode selection is determined, at startup, by a 47 kOhm pullup/pull-
down on this line. A pullup to VL selects Master mode and a pulldown to GND selects
Slave mode.
Analog Power
5
VA (
Input) - Analog power supply. Typically 1.8 to 3.3 VDC.
Ground
6
GND (
Input) - Ground Reference.
CS5333
12
DS520PP1
Left/Right Clock
7
LRCK (
Input/Output) - The Left/Right clock determines which channel is currently being
output on the serial audio data line SDOUT. The frequency of the Left/Right clock must be
at the input sample rate. The required relationship between the Left/Right clock, serial
clock and serial data is defined by the DIF pin.
MCLK Divide
Enable
8
DIV (
Input) - This pin serves different functions in Master and Slave modes.
In Master mode: When high, the chip will enter High Rate Mode; When this pin is low, the
chip will enter Base Rate Mode.
In Slave mode: When high, MCLK is divided internally by 2; When low, MCLK is not
changed.
Digital Interface
Format
9
DIF (
Input) - The required relationship between the Left/Right clock, serial clock and serial
data is defined by the Digital Interface Format.
Test Input
10
TST (
Input) - Must be connected directly to ground.
Positive Voltage
Reference
11
FILT+ (
Output) - Positive reference for internal sampling circuits. An external capacitor is
required from FILT+ to ground, as shown in Figure 3. The recommended value will typi-
cally provide 60 dB of PSRR at 1 kHz and 40 dB of PSRR at 60 Hz. FILT+ is not intended
to supply external current. FILT+ has a typical source impedance of 250 k
and any cur-
rent drawn from this pin will alter device performance.
Reference Ground
12
REF_GND (
Input) - Ground reference for the internal sampling circuits. Must be con-
nected to ground.
Analog Inputs
13,14
AINR, AINL (
Input) - The full scale analog input level is specified in the Analog Character-
istics specification table.
Quiescent Voltage
15
VQ (
Output) - Filter connection for internal A/D converter quiescent reference voltage. A
capacitor must be connected from VQ to ground. VQ is not intended to supply external
current. VQ has a typical source impedance of 250 k
and any current drawn from this pin
will alter device performance.
Reset
16
RST (
Input) - When low the device enters a low power mode and the part is in reset.
When high, the part returns to normal operation within 1024 LRCK cycles.

4. APPLICATIONS
4.1
Grounding and Power Supply
Decoupling
As with any high resolution converter, the CS5333
requires careful attention to power supply and
grounding arrangements to optimize performance.
Figure 3 show the recommended power arrange-
ment with VA and VL connected to clean supplies.
Decoupling capacitors should be located as close to
the device package as possible.
4.2
Oversampling Modes
The CS5333 operates in one of two oversampling
modes. Base Rate Mode supports input sample
rates up to 50 kHz while High Rate Mode supports
input sample rates up to 100 kHz. See Table 1 for
more details.
4.3
Recommended Power-up Sequence
1) Hold RST low until the power supply, master,
and left/right clocks are stable. In this state, VQ
will remain low.
2) Bring RST high. The device will remain in a
low power state with VQ low and will initiate
the power-up sequence. This power-up se-
quence takes approximately 1024 LRCK cycles
to complete.
4.4
Master/Slave Mode
In Master, Base Rate Mode (Pull-up on SDATA,
DIV=0), the CS5333 requires a 256x MCLK and
provide a 64x SCLK. In Master, High Rate Mode
(Pull-up on SDATA, DIV=1), the CS5333 requires
a 128x MCLK and provide a 64x SCLK. The vari-
ous clocking ratios required in Slave Mode (Pull-
down on SDATA) are listed under the description
of MCLK, on page 11.

5. PARAMETER DEFINITIONS
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
bandwidth (typically 10 Hz to 20 kHz), including distortion components. Expressed in decibels.
Dynamic Range
The ratio of the full scale 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 measurement over the specified bandwidth
made with a -60 dBFS signal. 60 dB is then added to the 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 So-
ciety, AES17-1991, and the Electronic Industries Association of Japan, EIAJ CP-307.
Interchannel Isolation
A measure of crosstalk between the left and right channels. Measured for each channel at the converter's
output with all zeros to 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 output for a full scale digital input.
Gain Drift
The change in gain value with temperature. Units in ppm/C.
