Other Parts Discussed in Thread: ISO7340-Q1, PCM2706
I plan to operate PCM2706C in bus-powered mode as a USB-to-I2S transport with digital isolation.
Can the internal VDD regulator of PCM2706C supply enough current to power VCC1 supply of ISO7340-Q1 (listed as 1.3mA @ 10Mbps)?
I would be passing PCM2706 DOUT, I2S bit clock, I2S frame sync, and SSPND_N signals through ISO7340-Q1.
Side question: can C_VCOM be changed to 1uF ceramic cap if DAC outputs are not being used?
