DESCRIPTION

TSSOP20

NAME

NO.

Dependent on SMBus settings, CLK_IN0 is the crystal-oscillator input and can also be used as an

CLK_IN0

LVCMOS input or as positive differential signal inputs.

Depending on SMBus settings, CLK_IN1 serves as the crystal oscillator output or can be the

CLK_IN1

I/O

second LVCMOS input or the negative differential signal input.
