Function

CLKa, /CLKa

LVPECL, LVECL, HSTL Clock Input: CLKa input includes a 75kΩ pull-down. Default is LOW if left floating.

/CLKa includes both pull-up and pull-down resistors. Default condition is VCC/2.

CLKb, /CLKb

LVPECL, LVECL, HSTL Clock Input: CLKb input includes a 75kΩ pull-down. Default is LOW if left floating.

/CLKb includes both pull-up and pull-down resistors. Default condition is VCC/2.

Qn0:4, /Qn0:4

LVPECL or LVECL Outputs: Terminate to VCC–2V. (see “Termination” section)

V

BB

Reference Voltage for Single-Ended Inputs: It provides the switching reference for the input differential amplifier.

When used, bypass with a 0.0µF capacitor to the most positive reference (usually VCC) as shown in Figure 3.

V

CC

Positive Power Supply: For LVPECL operation, connect VCC to 3.3V or 2.5V. For LVECL operation, connect to

GND. Bypass with 0.1µF//0.01µF low ESR capacitors.

V

EE

Negative Power Supply: For LVPECL operation, connect to GND. For LVECL operation, connect to –3.3V or

–2.5V.
