ADF4169 READBACK

Hi all,

 

For frequency readback, the following sequence is described in the datasheet @ ADF4169.


Figure 2. Write Timing Diagram
Figure 3. Read Timing Diagram
Figure 50. Reading Back Single Bits to Determine the Output Frequency at the Moment of Interrupt
Figure 51. Continuous Frequency Readback

 

Figure 2,3,50 is the same sequence, timing pulsed on TXDATA, LE.

 

But the timing pulsed on TXDATA, LE @ Figure 51 are difference from Figure 2,3,50

I cannot understand the timing pulsed on TXDATA, LE @ Figure 51.

Why is the difference timing / control ? 

 

Best regards,

sss
