CS5340 4.APPLICATIONS 4.1 Single-, Double-, and Quad-Speed Modes The CS5340 can support output sample tates from 2 kHz to 200 kHz. The proper speed mode can be de-termined by the desired output sample rate and the extemal MCLK/LRCK ratio, as shown in Table 1. Speed Mode MCLK/LRCK Ratio Output Sample Rate Range (kHz) Single-Speed Mode 512x 43-50 256x 2-50 Doubte-Speed Mode 256x 86-100 128x 4-100 - Quad-Speed Mode 128x 172 - 200 64x" 100-200 Quad-Speed Mode. 64x onty avallable In Masler Mode.

CS5340 4.2.3 Master Clock The CS5340 requires a Master clock (MCLK) which runs the internai sampling circuits and digital filters. There is also an internai MCLK divider which is automatically activated based on the speed mode and frequency of the MCLK. Table 3 shows a listing of the externat MCLK/LRCK ratios that are required. Table 4 lists some common audio output sample rates and the required MCLK frequency. Please note (hat not ail of the listed sample rates are supported when operating with a fast MCLK (512x, 256x, 128x for Single-. Double-, and Quad-Speed Modes, respectively)....

CIRRUS LOGIC CS5340 4.4 Power-Up Squence Reliable power-up can be accomplished by keeping the device in reset until the power supplies, docks and configuration pins are stable. It is also recommended tha reset be enabled if the analog or digital supplies drop below the minimum specified operating voltages to prevent power-glitch-related issues* 4.5 Analog Connections The analog modulatorsamplesthe input at half of the MCLKfrequency, or nominally 6.144 MHz. The digital filter will reject signais within the stopband of the filter. Howevert there is no rejection for input signais which are...
