| 3.3V/5V DUAL LVTTL/LVCMOS-toDIFFERENTIAL LVPECL TRANSLATOR FEATURES s s s s s s s s s 3.3V and 5V power supply option 300ps typical propagation delay Differential LVPECL outputs ICC Max 25mA PNP LVTTL inputs for minimal loading Flow-through pinouts Q outputs will default HIGH with inputs open Max. frequency range 800MHz Available in 8-pin MSOP and SOIC package SY100EPT22V DESCRIPTION The SY100EPT22V is a dual TTL/CMOS to differential PECL translator. Capable of running from a 3.3 or 5V supply, the part can be used in either LVTTL/LVCMOS/ LVPECL or TTL/CMOS/PECL systems. The device only requires a single positive supply of 3.3V or 5V - no negative supply is required. The tiny 8-pin MSOP package and the low skew, dual gate design of the EPT22V makes it ideal for those applications where space, performance, and low power are at a premium.
