Interfacing ADAU1701 with AD1955

I am trying to send the I2S output from ADAU1701 acting as master to a DAC board built around the AD1955. Questions:

1. The ADAU1701 datasheet recommends on p18 that MP11 be used to derive MCLK. Now MP11 also serves the purpose of OUTPUT_BCLK when used for I2S. Therefore does this mean that I can connect MCLK and BCLK together?

2. The ADAU1701 operates at 3V3 and AD1955 at 5V. Is the ADG3304 a good choice to perform the voltage level translation between the two at these frequencies?

Thank you - Ram
