PLL1705: I2S Controller

matt holland

Part Number: PLL1705
Other Parts Discussed in Thread: TAS5753MD, CDCE913

If I have two I2S audio sources configured as slaves driving a TAS5753MD speaker amplifier, is there a simple I2S "controller" IC that can generate the SCLK and LRCLK to all three? Something like the PLL1705 which has the appropriate additional divided down outputs?

Dear Matt,

It looks like you are looking for a master audio clock with correct divider to do the left right clock. I recommend you look at CDCE913. You could use the device in Xtal mode with a 24.576 MHz master clock and divide down by 512 and 8 for example to generate the clock you need. This device is very flexible as it has a PLL. Let us know if you have questions.

Regards, Simon.
