GENERAL DESCRIPTION

The 85320I is a LVCMOS / LVTTL-to-Differential 3.3V, 2.5V LVPECL

translator. The 85320I has a single ended clock input. The single

ended clock input accepts LVCMOS or LVTTL input levels and

translates them to 3.3V or 2.5V LVPECL levels. The small outline

8-pin SOIC package makes this device ideal for applications where

space, high performance and low power are important.

FEATURES

• One differential 2.5V/3.3V LVPECL output

• LVCMOS/LVTTL CLK input

• CLK accepts the following input levels: LVCMOS or LVTTL

• Maximum output frequency: 267MHz

• Part-to-part skew: 275ps (maximum)

• Additive phase jitter, RMS: 0.05ps (typical)

• 3.3V operating supply voltage

(operating range 3.135V to 3.465V)

• 2.5V operating supply voltage

(operating range 2.375V to 2.625V)

• -40°C to 85°C ambient operating temperature

• Available in lead-free (RoHS 6) package
