DESCRIPTION
The SY89223L is a 3.3V, precision dual differential
LVPECL-to-LVTTL translator. The ultra-small 8-pin MLF
package and the low skew, dual gate design of this
translator makes it ideal for applications which require
the translation of a clock and a data signal.
The SY89223L translator accepts 10k or 100k
differential LVPECL inputs.

Permanent device damage may occur if ABSOLUTE MAXIMUM RATINGS are exceeded. This is a stress rating only and functional operation is
not implied at conditions other than those detailed in the operational sections of this data sheet. Exposure to ABSOLUTE MAXIMUM RATlNG
conditions for extended periods may affect device reliability.
The data sheet limits are not guaranteed if the device is operated beyond the operating ratings.
Package thermal resistance assumes exposed pad is soldered (or equivalent) to the device's most negative potential on the PCB.
