DESCRIPTION
The SY89222L is a dual TTL-to-differential LVPECL
translator with a +3.3V power supply. Because LVPECL
(Positive ECL) levels are used, only +3.3V and ground are
required. The SY89222L is functionally equivalent to the
SY100ELT22L but in an ultra-small 8-lead MLF鈩?package
that features a 70% smaller footprint. The low skew, dual
gate design of the SY89222L makes it ideal for applications
that require the translation of a clock and a data signal.
