Analog Devices Inc. AD9209 Quad 12-Bit 4GSPS Analog-to-Digital Converter (ADC) has an on-chip wideband buffer with overload protection. This device supports applications capable of direct sampling wideband signals up to 8GHz. An on-chip, low-phase noise, phase-locked loop (PLL) clock synthesizer is available to generate the ADC sampling clock. This feature simplifies the distribution of a high-frequency clock signal's printed circuit board (PCB). A clock output buffer is available to transmit the ADC sampling clock to other devices.
