SY100EPT20V 3.3V/5V LVTTL/LVCMOS-to-Differential LVPECL Translator Features General Description 3.3V and 5V Power Supply Options The SY100EPT20V is a TTL/CMOS to differential PECL translator. Capable of running from a 3.3V or 5V 300 ps Typical Propagation Delay supply, the part can be used in either Differential LVPECL Output LVTTL/LVCMOS/LVPECL or TTL/CMOS/PECL 2 0 mA Maximum Supply Current systems. PNP LVTTL Input for Minimal Loading The device only requires a single positive supply of Q Output will Default High with Inputs Open 3.3V or 5V. No negative supply is required. High Bandwidth up to 850 MHz Typical The tiny 8-lead MSOP package and the low-skew, Available in 8-Lead MSOP and SOIC Packages dual-gate design of the SY100EPT20V make it ideal for those applications where space, performance, and low power are at a premium.
