... In addition, an on-chip oscillator driver provides clocking flexibility and simplifies design. The CS5368 is the industry’s first audio A/D to support a high-speed TDM interface which provides a serial output of 8 channels of audio data with sample rates up to 216 kHz within a single data stream. It further reduces layout complexity and relieves input/output constraints in digital signal processors ...

... Control Port Mode. To use the CS5368 in Stand-Alone Mode, the configuration pins must be held in a stable state, at valid logic levels, and RST must be asserted until the power supplies and clocks are stable and valid. More informa- tion on the reset function is available in 4 ...

... Master Clock Source The CS5368 requires a Master Clock that can come from one of two sources: an on-chip crystal oscillator driver or an externally generated clock. 4.3.1 On-Chip Crystal Oscillator Driver When using the on-board crystal oscillator driver, the XTI pin (pin 21) is the input for the Master Clock (MCLK) to the device ...
Page 21
... To ensure synchronous sampling in applications where multiple ADCs are used, the MCLK and LRCK must be the same for all CS5368 devices in the system. If only one master clock source is needed, one solution is to place one CS5368 in Master Mode, and slave all of the other devices to the one master, as illustrated in Figure 9 ...
Page 22
... CS5368 will fill the longer frame with trailing zeros. If fewer than 24 SCLK cycles per channel are received from a master, the CS5368 will truncate the serial data output to the number of SCLK cycles received. For a complete overview of serial audio interface formats, please refer to Cirrus Logic Ap- plication Note AN282 ...

... Speed Modes 4.6.1 Sample Rate Ranges CS5368 supports sampling rates from 2 kHz to 21 kHz, divided into three ranges: 2 kHz - 54 kHz, 54 kHz - 108 kHz, and 108 kHz - 216 kHz. These sampling speed modes are called Single-Speed Mode (SSM), Double-Speed Mode (DSM), and Quad-Speed Mode (QSM), respectively. ...
Page 24
... The external MCLK is subject to clock dividers as set by the clock divider pins in Stand-Alone Mode or the clock divider bits in Control Port Mode. The CS5368 compares the divided- down, internal MCLK to the incoming LRCK/FS and sets the speed mode based on the MCLK/LRCK ratio ...

... RST pin low for a minimum of one MCLK cycle and then restoring the pin to a logic-high condition. 4.8.1 Power-Down Mode The CS5368 features a Power-Down Mode in which power is temporarily withheld from the modulators, the crystal oscillator driver, the digital core, and the serial port. The user can access Power-Down Mode by holding the device in reset and holding all clock lines at a static, valid logic level (either logic-high or logic- low) ...

... DC Offset Control The CS5368 includes a dedicated high-pass filter for each channel to remove input DC offset at the system level level may result in audible “clicks” when switching between devices in a multi-channel system. In Stand-Alone Mode, all of the high-pass filters remain enabled. In Control Port Mode, the high-pass filters default to enabled, but may be controlled by writing to the HPF register ...

... SDA while SCL is high. All other transitions of SDA occur while SCL is low. The first byte sent to the CS5368 after a Start condition consists of a 7-bit chip address field and a R/W bit (high for a read, low for a write). The upper five bits of the 7-bit address field are fixed at 10011. To communicate with a CS5368, the chip address field, which is the first byte sent to the CS5368, should match 10011 and be followed by the settings of the AD1 and AD0 ...
