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.
