ECL Pro™ SY10EPT20V SY100EPT20V FINAL 5V/3.3V LVTTL/LVCMOS-toDIFFERENTIAL LVPECL TRANSLATOR FEATURES ■ ■ ■ ■ ■ ■ ■ ■ 3.3V and 5V power supply options 300ps typical propagation delay Differential LVPECL output ICC Max 20mA PNP LVTTL input for minimal loading Q output will default HIGH with inputs open High bandwidth to 800MHz typical Available in 8-pin MSOP and SOIC package ECL Pro™ DESCRIPTION The SY10/100EPT20V is a 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 EPT20V makes it ideal for those applications where space, performance, and low power are at a premium.
