THEORY OF OPERATION The AD9219 architecture consists of a pipelined ADC divided into three sections: a 4-bit first stage followed by eight 1.5-bit stages and a final 3-bit flash. Each stage provides sufficient overlap to correct for flash errors in ...

Page 21
For best dynamic performance, the source impedances driving VIN + x and VIN − x should be matched such that common- mode settling errors are symmetrical. These errors are reduced by the common-mode rejection of the ADC. An internal reference ...
Page 22
AD9219 CLOCK INPUT CONSIDERATIONS For optimum performance, the AD9219 sample clock inputs (CLK+ and CLK−) should be clocked with a differential signal. This signal is typically ac-coupled to the CLK+ and CLK− pins via a transformer or capacitors. These pins ...
Page 23
Clock Jitter Considerations High speed, high resolution ADCs are sensitive to the quality of the clock input. The degradation in SNR at a given input frequency (f due only to aperture jitter (t ) can be calculated by J SNR ...
Page 24
AD9219 By asserting the PDWN pin high, the AD9219 is placed into power-down mode. In this state, the ADC typically dissipates 3 mW. During power-down, the LVDS output drivers are placed into a high impedance state. If any of the ...

AD9219 Two output clocks are provided to assist in capturing data from the AD9219. The DCO is used to clock the output data and is equal to five times the sample clock (CLK) rate. Data is clocked out of the ...
Page 27
When the SPI is used, the DCO phase can be adjusted in 60° increments relative to the data edge. This enables the user to refine system timing margins if required. The default DCO+ and DCO− timing, as shown in Figure ...

AD9219 SCLK/DTP Pin The SCLK/DTP pin is for use in applications that do not require SPI mode operation. This pin can enable a single digital test pattern if it and the CSB pin are held high during device power- up. ...
