ADL5202 can be configured in many different ways depending on the application therefore the parts in the input and output path are left unpopulated Users should see the ADL5202 data sheet for additional information on this part and for configuring the inputs and outputs The ADL5202 by default is held in power down mode but can be enabled by adding 1 resistors at R427 and R428 to enable Channel A and Channel B respectively Clock Circuitry The default clock input circuit that is populated on the AD9643 AD9613 AD6649 AD6643 evaluation board uses a simple transformer coupled circuit with a high bandwidth 1 1 impedance ratio transformer T503 that adds a very low amount of jitter to the clock path The clock input is 50 terminated and ac coupled to handle single ended sine wave types of inputs The transformer converts the single ended input to a differential signal that is clipped by CR503 before entering the ADC clock inputs The board is set by default to use an external clock generator An external clock source capable of driving a 50 O terminated input should be connected to 506 A differential LVPECL clock driver output can also be used to clock the ADC input using the AD9523 U501 To place the AD9523 into the clock path populate R541 and R542 with 0 Q resistors and remove C532 and C533 to disconnect the default clock path inputs In addition populate R533 and R534 with 0 resistors remove R522 and R523 to disconne
