14.318 MHz output.
Latched input for FS1 at initial power up for H/W selecting the
output frequency clocks. This is internal 120KΩ pull up.
14.318 MHz output.
Latched input for FS0 at initial power up for H/W selecting the
output frequency clocks. This is internal 120KΩ pull up.
14.318 MHz output.
48 MHz clock output.
Latched input at initial power up for 24_48 MHz selecting the output
frequency clocks. This is internal 120KΩ pull down, 1 = 24 MHz, 0
= 48 MHz (default).
48 MHz clock output.
Latched input for FS3 at initial power up for H/W selecting the
output frequency clocks. This is internal 120KΩ pull down.
48 MHz clock output.
