FEATURES
s s s s s s s 3.3V power supply 300ps typical propagation delay <100ps output-to-output skew Differential LVPECL outputs PNP TTL inputs for minimal loading Flow-through pinouts Available in ultra-small 8-pin MLFTM (2mm x 2mm) package Precision Edge(R)
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 MLFTM 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.

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 devices most negative potential on the PCB. Parametric values specified at: 3 volt power supply range +3.0V to +3.8V. Output loaded with 50 to VCC-2V.

AC parameters are guaranteed by design and characterization. Same transition, common VCC levels. Cycle-to-cycle jitter definition: the variation in the period between adjacent cycles over a random sample of adjacent cycle pairs: Tjitter_CC = Tn - Tnt , where T is the time between the rising edges of the output cycle.
