I/O DESCRIPTION
NAME NO.
V
CC
3, 25 3.3-V supply voltage
Crystal 1/48-MHz clock input. When MODE is low, XTAL1/CLK48 is a 6-MHz crystal input with 50% duty cycle. An
XTAL1/CLK48 30 I internal APLL generates the 48-MHz and 12-MHz clocks used internally by the ASIC logic. When MODE is high,
XTAL1/CLK48 acts as the input of the 48-MHz clock and the internal APLL logic is bypassed.
XTAL2 29 O Crystal 2. XTAL2 is a 6-MHz crystal output. This terminal must be left open when using an oscillator.

(1) Stresses beyond those listed under “absolute maximum ratings” may cause permanent damage to the device. These are stress ratings
only, and functional operation of the device at these or any other conditions beyond those indicated under “recommended operating
conditions” is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
(2) All voltage levels are with respect to GND.
