1 www.semtech.comRevision 1/October 16, 2001 SK10/100ELT21W Differential PECL to CMOS/TTL or LVPECL to LVCMOS/LVTTL Translator Description Features Functional Block Diagram PIN Names The SK10/100ELT21W is a single differential PECL to CMOS/TTL or LVPECL to LVCMOS/LVTTL Translator. Since PECL (Positive ECL) levels are used, only +V CC and ground are required. The small outline, 8 lead SOIC package, low skew, and the single gate design of the SK10/100ELT21W makes it ideal for applications which require the translation of a clock and a data signal. Unlike the TTL totem pole outputs, the outputs of the ELT21W can be interfaced directly to CMOS inputs with better VOH (VCC – 0.5V) levels. With extended supply voltage capability, the device is functionally compatible with MC10/100ELT21 (5V) and MC10/100LVELT21 (3.3V).

CMR range is referenced to the most positive side of the differential input signal. Normal operation is obtained if the high level falls within the specified range and the peak-to-peak voltage lies between VPP (min) and 1V . The lower end of the CMR range varies 1:1 with GND and is equal to GND + 1.2V . 3. C L = 20 pF. 4. For part ordering description, see HPP Part Ordering Information Data Sheet.
