case a 2 kHz, 4 kHz, 8 kHz, or 1PPS signal can be input on this pin.
CMOS
IN10: Input Clock 10
A reference clock is input on this pin. This pin can also be used as a sync input, and in this
case a 2 kHz, 4 kHz, 8 kHz, or 1PPS signal can be input on this pin.
CMOS
IN11: Input Clock 11
A reference clock is input on this pin. This pin can also be used as a sync input, and in this
case a 2 kHz, 4 kHz, 8 kHz, or 1PPS signal can be input on this pin.
CMOS
IN12: Input Clock 12
A reference clock is input on this pin. This pin can also be used as a sync input, and in this
case a 2 kHz, 4 kHz, 8 kHz, or 1PPS signal can be input on this pin.
CMOS
IN13: Input Clock 13
