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.
The D input is internally biased to V_DD/2. A sine wave input of at least 750 mv p-p ensures the AZP51 series
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.
