| Micrel, Inc. QUAD CMOS-to-PECL TRANSLATOR SY10H352 SY10H352 FEATURES s s s s s s Single 5V power supply All VCC pins isolated on chip Differentially drive balanced lines tpd 1.3ns typical Fully compatible with MC10H352 Available in 20-pin PLCC package DESCRIPTION The SY10H352 is a quad translator for interfacing data between a CMOS logic section and the PECL section of digital systems when only a +5.0V VDC power supply is available. The SY10H352 has CMOS compatible inputs and PECL complementary open-emitter outputs that allow use as an inverting/non-inverting translator or as a differential line driver. When the common strobe input is at a low logic level, it forces all true outputs to the PECL low logic state ( +3.2V) and all inverting outputs to the PECL high logic state ( +4.1V). The SY10H352 can also be used with the SY10H350 to transmit and receive CMOS information differentially via balanced twisted pair lines.
