DESCRIPTION

The AZP51 series is a family of sine wave to LVPECL buffers optimized for low phase noise. It is particularly

useful in converting sine wave crystal or SAW based oscillator outputs into LVPECL outputs. The IC also includes

an optional ÷2 function to provide better frequency range coverage when using a SAW based oscillator.

meets its AC specifications. This input (D) should be capacitively coupled from the oscillator stage to ensure best

output duty cycle.

AZP51S (÷1), AZP52S (÷2), SC-70 Package

The Enable input (EN) is active high with an internal pullup. When EN is high or not connected, the outputs

(Q,Q

¯ ) are active. When EN is low, Q and Q

¯ are disabled in a high impedance (tri-state) condition. Refer to the

Functional Operation table for more information.

AZP53P (÷1, ÷2), QFN 8 1.5x1.5mm Package

The EN_SEL input selects the operational polarity for the EN input, so the EN input can be set to active high or

active low operation. Refer to the Functional Operation table for more information.
