Micrel, Inc. 3.3V DIFFERENTIAL LVPECL-to-LVTTL TRANSLATOR ECL Pro™ SY100EPT21L ECL Pro™ SY100EPT21L FEATURES ■ Guaranteed over the industrial temperature range: –40°C to +85°C ■ Pin-for-pin; plug-in replacement to MC100EPT21D/DT ■ 3.3V power supply ■ 1.9ns typical propagation delay ■ 275MHz fMAX (Clock) ■ Differential LVPECL inputs ■ 24mA LVTTL output ■ Flow-through pinout ■ Q output will default LOW with inputs open ■ VBB output ■ Available in 8-pin MSOP and SOIC packages ECL Pro™ DESCRIPTION The SY100EPT21L is a single, differential LVPECLto-LVTTL translator using a single +3.3V power supply. Because low voltage positive ECL (LVPECL) levels are used, only +3.3V and ground are required. The small outline 8-pin SOIC package and low-skew, single-gate design make the EPT21L ideal for applications that require the translation of a clock or data signal where minimal space, low power, and low cost are critical. VBB allows a differential, single-ended, or AC-coupled interface to the device. If used, the VBB output should be bypassed to VCC with 0.01µF capacitor. Under open input conditions, the /D will be biased at a VCC/2 voltage level and the D input will be pulled to ground. This condition will force the Q output low to provide added stability. The 100EPT is compatible with positive ECL 100K logic levels. For applications that require the smallest footprint, consider the SY89321L in an ultra-small (2mm × 2mm) 8-pin MLF™ package.
