DESCRIPTION

■3.3V power supply

■1.9ns typical propagation delay

■Maximum frequency > 275MHz

■Differential LVPECL inputs

■24mA LVTTL outputs

■Flow-through pinouts

■Internal input resistors: pulldown on D, pulldown

and pullup on /D

■Q output will default LOW with inputs open or at

Ground

■Available in 8-pin MSOP and SOIC packages

The SY100EPT23L is a dual differential LVPECL-to-

LVTTL translator. Because LVPECL (Low Voltage Positive

ECL) levels are used, only +3.3V and ground are required.

The tiny 8-pin MSOP and dual-gate design of the EPT23L

makes it ideal for applications which require the

translation of a clock and data signal.

The EPT23L is available in only the ECL 100K

standard. Since there are no LVPECL outputs or an

external VBB reference, the EPT23L does not require

both ECL standard versions. The inputs can accept 10K

voltage levels and any standard differential LVPECL input

referenced from a VCC of +3.3V
