evaluation board user guide ug- 390 rev. 0 | page 3 of 8 evaluation board configuration setting u p the e valuation b oard the eval - ad n469xeh d ebz allows the adn469 0 e / adn469 1 e / adn469 4 e / ad n4696e to be quickly and easily evaluated. the evaluation board allows all of the input and output functions to be exercised without the need for external component s. jumper configurations are shown in table 2 . the board is powered by connecting a 3.3 v power supply to the screw terminals for vcc and gnd. supply current is typically 16 ma with both driver and receiver enab led, or 1 ma with both disabled. a 10 f decoupling capacitor , c1 , is fitted at the connector between v cc and gnd. the vcc pin of the adn469xe is fitted with a decoupling c apacitor of 100 nf . an example evaluation of the adn469 0 e / adn469 1 e / adn469 4 e / ad n4696e driver is shown in figure 2 . a signal generator is connected to di with an input signal of 50 mhz ( adn469 0 e / adn469 4 e ) or 100 mhz ( adn469 1 e / ad n4696e ), with a 50% duty cycle and swing of between 0 v and 3.3 v. jumper s lk1 and lk2 are connected in p osition a to disable the receiver and enable the driver. oscillos cope probes are connected to di, a , and b . similarly, an evaluation of the adn469 0 e / adn469 1 e / adn469 4 e / ad n4696e receiver is shown in figure 3 . a signal generator capable of applying a differential input signal is connected to j5 and j6 , with the in put swing between 1 v and 1.2 v (j6 input the inverse of j5 input ) . jumpers lk1 and lk2 are connected in p osition b to enable the receiver and disable the driver. oscilloscope probes are attached to ro, a , and b. evaluation with appl ications tw o e va l - adn469xe h debz boards can be connected together in a point - to - point configuration as shown in figure 4 . in or der to allow part evaluation with a load equivalent to a parallel - terminated bus, the boards have been fitted with 50 termination resistors. for the point - to - point configuration in figure 4 , these should be replaced with resistors of 100 . a signal generator is connected onto one boards di input. this boards a and b outputs are respectively c onnected to the second boards a and b inputs. connecting probes to di on the first board, and a, b , and ro on the second, the propagation of the input signal across the bus and to the receiver output of the second board can be observed and evaluated. alte rnatively, the eval - adn469xe h debz can be connected to an existing bus and a control board as shown in figure 5 in order to test the performance in the application. in this case, both termination resistors should be removed, as wel l as the jumpers on lk1 and lk2. control signals should be connected to ro, re , de , and di. re j2 lk1 lk2 de j3 di j4 b a j6 a b j5 ro j1 ro de re di gnd gnd gnd gnd j9 vcc 3.3v power supply signal generator eval-adn469xehdebz oscilloscope 10615-002 figure 2. adn469 0 e / adn469 1 e / adn469 4 e / ad n4696e driver evaluation with eval - adn469xehdebz re j2 lk1 lk2 de j3 di j4 b a j6 a b j5 ro j1 ro de re di gnd gnd gnd gnd j9 vcc eval-adn469xehdebz 3.3v power supply signal generator oscilloscope 10615-003 figure 3. adn469 0 e / adn469 1 e / adn469 4 e / ad n4696e receiver evaluation with eval - adn469xehdebz
