• Manufacturer Part Number: cs4360
• Description: 24-bit, 192 Khz 6-channel D/a Converter
• Manufacturer: Cirrus Logic, Inc.

4.3.2
The desired format is selected via the DIF2, DIF1 and DIF0 bits in the Mode Control 2 register (see section
6.1.2). For an illustration of the required relationship between LRCK, SCLK and SDIN, see Figures 15-17.
4.4
The device includes on-chip digital de-emphasis. Figure 18 shows the de-emphasis curve for F
44.1 kHz. The frequency response of the de-emphasis curve will scale proportionally with changes in
sample rate, Fs.
Notes: De-emphasis is only available in Single-speed Mode.
