Table 2. Programmable Skew Configurations(1)
Notes:
1. For all three-state inputs, HIGH indicates a connection to VCC, LOW indicates a connection to GND, and MID indicates an
open connection. Internal termination circuitry holds an unconnected input to VCC/2.
2. The level to be set on FS is determined by the “normal” operating frequency (fNOM) and Time Unit Generator
(see Logic Block Diagram). Nominal frequency (fNOM) always appears at 1Q0 and the other outputs when they are operated in
their undivided modes (see Table 2). The frequency appearing at the REF and FB inputs will be f NOM when the output connected
to FB is undivided. The frequency of the REF and FB inputs will be fNOM/2 or fNOM/4 when the part is configured for a frequency
multiplication by using a divided output as the FB input.
