Advanced Multi-bit Delta-Sigma Architecture 24-bit Conversion Supports all audio sample rates including 192 kHz. 105 dB Dynamic Range at 5 V -98 dB THD+N High-pass Filter to Remove DC Offsets Analog/digital Core Supplies from 3.3 V to 5 V Supports logic levels between 1.8 V and 5 V. Low-latency Digital Filter Auto-mode Selection General Description The CS5341 is a complete analog-to-digital converter for digital audio systems. It performs sampling, analog-to- digital conversion, and anti-alias filtering, generating 24-bit values for both left and right inputs in serial form at sample rates up to 200 kHz per channel. The CS5341 uses a 5th-order, multi-bit Delta-Sigma modulator followed by digital filtering and decimation, which removes the need for an external anti-alias filter. The CS5341 is ideal for audio systems requiring wide dy- namic range, negligible distortion and low noise, such as set-top boxes, DVD-karaoke players, DVD recorders, A/V receivers, and automotive applications.

APPLICATIONS
4.1 Single, Double, and Quad Speed Modes The CS5341 can support output sample rates from 2 kHz to 200 kHz. The proper speed mode can be determined by the desired output sample rate and the external MCLK/LRCK ratio, as shown in Table 1. * Quad Speed Mode, 64x only available in Master Mode. Table 1. Speed Modes and the Associated Output Sample Rates (Fs) or slave is made via the Mode pins as shown in Table 2. Table 2. CS5341 Mode Control
the master clock with the left/right clock equal to Fs and the serial clock equal to 64x Fs, as shown in Figure 18. be synchronously derived from the master clock and be equal to 64x Fs to maximize system performance. to the desired mode. The auto-mode selection feature supports all standard audio sample rates from 2 to 200 kHz. Figure 18. CS5341 Master Mode Clocking

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 bandwidth made with a -60 dBFS signal. 60 dB 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 affect 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 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. 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 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 input for a full-scale digital output. Gain Drift The change in gain value with temperature. Units in ppm/°C. Offset Error
