AZP53
Low Phase Noise Sine Wave / CMOS
to LVPECL Buffer / Translator
DESCRIPTION
The AZP53 is a sine wave/CMOS to LVPECL buffer/translator optimized
for very low phase noise (-165dBc/Hz). It is particularly useful in
converting crystal or SAW based oscillators into LVPECL outputs for up
800MHz of bandwidth. For greater bandwidth, refer to the AZP63.
The AZP53 is one of a family of parts that provide options of fixed ÷1,
fixed ÷2 and selectable ÷1, ÷2 modes as well as active high enable or active
low enable to oscillator designers. Refer to Table 2 for the comparison of
parts within the AZP5x and AZP63 family.
