DESCRIPTION
CMOS Local Clock : A 25Mhz clock, +/- 100 ppm, 40%-60% duty
cycle.
Crystal Oscillator Input : A 25Mhz crystal, +/- 25 ppm can be
connected across XTALIN and XTALOUT.
Crystal Oscillator Output : A 25Mhz crystal, +/- 25 ppm can be
connected across XTALIN and XTALOUT. If a single-ended external
clock (LCLK) is connected to XTALIN, the crystal output pin should
be left floating.
Clock Output 25MHz : This clock is source from LCLK/XTALIN.
Reset
Reset is active high then place AX88195 into reset mode immediately.
During Falling edge the AX88195 loads the power on setting data.
User can select either RESET or /RESET for applications.
/Reset
Reset is active low then place AX88195 into reset mode immediately.
During rising edge the AX88195 loads the power on setting data.
User can select either RESET or /RESET for applications.
No Connection : for manufacturing test only.
