Product Details

The AD9209 is a quad, 12-bit, 4 GSPS analog-to-digital converter (ADC). The ADC input features an on-chip wideband buffer with overload protection. This product is designed to support communications applications capable of direct sampling wideband signals with a range up to 7.5 GHz. An optional low phase noise phase-locked loop (PLL) clock synthesizer is available to generate the ADC sampling clock, simplifying printed circuit board (PCB) distribution of a high frequency clock signal. Alternatively, the CLKIN of the device can be driven directly with the ADC sampling clock (or a higher version up to 12 GHz when the internal clock divider is enabled). An optional CLKOUT buffer is available to transmit the ADC sampling clock to other devices.
