3.3 V Dual LVTTL to DIfferential LVPECL Translator
FEATURES
1
⢠450 ps (typ) Propagation Delay
⢠Operating Range: VCC 3.0 V to 3.8 with
GND = 0 V
⢠<50 ps (max) Output to Output Skew
⢠Built-in Temperature Compensation
⢠Drop in Compatible to MC100LVELT22

⢠Data and Clock Transmission Over Backplane
⢠Signaling Level Conversion for Clock or Data
DESCRIPTION
The SN65ELT22 is a dual LVTTL to differential LVPECL translator buffer. It operates on +3V supply and ground
only. The output is driven default high when the inputs are left floating or unused. The low output skew makes
the device the ideal solution for clock or data signal translation.
The SN65LVELT22 is housed in an industry standard SOIC-8 package and is also available in TSSOP-8
package option.
