puts. The PCLK, nPCLK input pairs can accept LVPECL, LVDS,
CML or SSTL levels. The fully differential architecture and low
propagation delay make it ideal for use in clock distribution cir-
cuits. The select pins have internal pulldown resistors. The SEL2
pin is the most significant bit and the binary number applied to
the select pins will select the same numbered data input (i.e.,
000 selects PCLK0, nPCLK0).
