Note C7:
Clock Leak
(1)
Input f = 225fH, Lev = 0.3Vp-p signal to pin 11.
(2)
Pin 13 and 15 are no input. (S1, S2 = b)
(3)
Measure clock level (225fH component) with spectrum analyzer at pin 11. (Vin [dB])
(4)
Measure clock level (225fH component) with spectrum analyzer at pin 16 and 19. (Vout [dB])
(6)
Measure clock leak.
