Note *: SEL pins should be controlled by 1.8V LVTTL logic; 3.3V tolerant.
Note 1: Outputs are user programmable to drive single-ended 1.8V/2.5V/3.3V LVTTL as indicated above.
Note 2: Default configuration CLK3=Buffered Reference output. All other outputs are off.
Note 3: Do not power up with SEL[1:0] = 00 (in Power down/Sleep mode).
