描述
The 853S12I is a low skew, 1-to-12 Differential-to- 3.3V, 2.5V LVPECL Fanout Buffer and a member of the HiPerClockS™ family of High Performance Clock Solutions from IDT. The PCLK, nPCLK pair accepts LVPECL, CML, and SSTL differential input levels. The high gain differential amplifier accepts peak-to-peak input voltages as small as 150mV, as long as the common mode voltage is within the specified minimum and maximum range. Guaranteed output and part-to-part skew characteristics make the 853S12I ideal for those clock distribution applications demanding well defined performance and repeatability.
