| CTSLV353 Low Phase Noise LVPECL Buffer and Translator QFN8, SON8 LVPECL Outputs Optimized for Very Low Phase Noise -165dBc/Hz Up to 800MHz Bandwidth Selectable ÷1, ÷2 Output Selectable Enable Logic 3.0V to 3.6V Operation RoHS Compliant Pb Free Packages BLOCK DIAGRAM The CTSLV353 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 CTSLV363. The CTSLV353 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 1 for the comparison of parts within the CTSLV35x and CTSLV363 family. ENGINEERING NOTES Functionality Table 1 details the differences between the family parts to assist designers in selecting the optimal part for their design. Table 2 lists the specific CTSLV353 functional operation. Figure 1 plots the S-parameters of the D input.
