Hello,
I have a question about the dac update rate and band width of AD9219.
On the "FEATURES" of datasheet the bandwidth is limited under 1GHz when using 2x interpolation mode.
But 2x interpolation mode enables 5.7GSPS update rate in the "GENERAL DESCRIPTION".
The DAC core is based on a quad-switch architecture that enables dual-edge clocking operation,
effectively increasing the DAC update rate to 5.7 GSPS when configured for Mix-Mode™ or 2× interpolation.
The high dynamic range and bandwidth enable multicarrier generation up to 4.2 GHz.
I think 2x interpolation mode is able to have same bandwidth as MIxed-mode.
Could you explain me why 2x interpolation mode bandwidth is limited under 1GHz ?
Thank you,
ysuzuki
