PLL
(a) PLL mode (PLL_PDX = 1)
In this mode, the 256fs clock (MCLK) used by the CODEC block is generated from the clock (12, 13.5, 24 and
27MHz frequencies supported) which is input from MCLKIN, and BCLK and LRCK are output.
Sampling frequencies (fs) of 7.86kHz to 48kHz are supported.
fs setting
fs is set by setting the division ratio for each of the three frequency dividers (DIV1, DIV2, and DIV3) in respective
registers.
1. Set FCKI[2:0] for the MCLKIN frequency, results in 12MHz or 13.5MHz as the frequency input to DIV1.
2. Set DIV1, DIV2, and DIV3, while referring to the division ratio setting example table.
ex. "FCKI = 2, DIV1 = 125, DIV2 = 128, DIV3 = 2" in case of "MCLKIN = 24MHz, fs = 24kHz"
(b) EXT mode (PLL_PDX = 0)
In this mode, the 256fs clock (MCLK) from MCLKIN is input and used.
When ADF_MASTER is 1, BCLK and LRCK whose frequency is obtained by dividing the frequency of MCLKIN
are output.
When ADF_MASTER is 0, BLCK and LRCK are external inputs.
* In the CODEC block, BCLK and LRCK must be synchronized with MCLK.
In PLL mode (PLL_PDX = 1), operation must be performed in BCLK output mode (ADF_MASTER = 1). In EXT
mode (PLL_PDX = 0) and when ADF_MASTER is 0, BCLK and LRCK synchronized with MCLK must be input.
