11.2 Clock input
The configuration shown in Figure 30 is recommended for high-frequency applications. In
both cases, the choice of transformer is a compromise between cost and performance.
The ADC1443D series can be driven differentially (LVPECL, LVDS or SINE). A
single-ended LVCMOS signal connected to either pin CLKP or pin CLKM can also drive
the device (connect the complementary pin to ground using a capacitor). The LVPECL is
recommended for an optimal performance.
