Notes:
1. 1X designates that the output is a replica of CLKIN.
2. 2X designates that the output is twice the frequency of
CLKIN, and in phase.
3. 1X# means that the output is at the same frequency and
180°C out of phase (inverted) from CLKIN.
4. Ø1 will produce a ¼ duty cycle clock of CLKIN.
5. Ø2 will produce a ¼ duty cycle clock delayed 180° from
CLKIN.

DESCRIPTION
GROUND.
GROUND.
INV# Inverts Q1 when low. (-01 [divisor select -03, -07])
EN converts Q4 and Q5 to phase clocks when high.
FEEDBACK INPUT from output Q0.
INPUT for reference clock.
Power supply (+5V).
Power supply (+5V).
GROUND.
Q0 phase and frequency same as input (1X). Feed back to pin 5.
Q1 is a 1x clock in phase or 180° out of phase with input.
Q2 twice the frequency of Q0 (2x).
Q3 twice the frequency of Q0 (2x).
Q4 is either a 2X clock or a two-phase clock - see configuration table.
Q5 is either a 2X clock or a two-phase clock - see configuration table.
Power supply (+5V).
