DESCRIPTION
NAME
NO.
SUSPND
1
O
Suspend status. SUSPND is an active high output available for external logic power down operations.
During the SUSPEND mode, SUSPND is high. SUSPND is low for normal operation.
VCC
XTAL1/CLK48
9, 46
3.3-V supply voltage.
45
I
Crystal 1/48-MHz Clock Input. When MODE is low, XTAL1/CLK48 is a 6-MHz crystal input with 50%
duty cycle. An 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
All LED control are 3-stated during low-power suspend.
44
O
Crystal 2. XTAL2 is a 6-MHz crystal output. This terminal should be left open when using an oscillator.

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.
