Description
96
CMOS Local Clock: A 25Mhz clock, +/-50 PPM, 40%-60% duty
cycle. Note that the pin does not support 3.3V or 5V voltage supply.
Crystal Oscillator Input: A 25Mhz crystal, +/-50 PPM can be
connected across XTALIN and XTALOUT.
98
Crystal Oscillator Output: A 25Mhz crystal, +/-50 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.
27
Reset:
Reset is active low then place AX88196B into reset mode. During the
rising edge the AX88196B loads the power on setting data.
88 Test Clock Pins: As a clock input for ASIC testing only
No connection when normal operation
89 Enable TCLK in to ASIC as a main clock for test only.
No connection when normal operation
21 TEST mode select
Connect to ground when normal operation
23 TEST mode select
