AD9211 Chip Grade

We're using a pair of AD9211 300MSPS ADCS in a design and as a house keeping exercise we are now reading the chip ID and chip grade.

The reading of chip ID agrees with the datasheet (0x6) however the chip grade does not agree.

We read 0x2 whereas the datasheet indicates that 0x0 should be returned for the 300MSPS part.

The ICs have the correct top markings for the 300MSPS and from an ADC perspective are performing correctly.

Attached is a serial port capture of the two reads.

Please can you confirm that this is yet another mistake in the AD9211 datasheet?
