GENERAL DESCRIPTION
T h e ICS853310 is a low skew, high performance 1-to-8 Differential-to-3.3V LVPECL/ECL H iPerC lockSTM Fanout Buffer and a member of the H i P e r C l o c k S TM family of High Performance C l o c k Solutions from ICS. The PCLKx, nPCLKx pairs can accept LVPECL, LVDS, CML and SSTL differential input levels. The ICS853310 is characterized to operate from a 3.3V power supply. Guaranteed output and part-to-part s k e w characteristics make the ICS853310 ideal for those c l o c k distribution applications demanding well defined perf o r m a n c e and repeatability.

NOTE 3: VCMR min varies 1:1 with VEE, max varies 1:1 with VCC. VCMR is defined as the range within which the VIH level may vary, with the device still meeting the propagation delay specification. The VIL level must be such that the peak-to-peak voltage is less than 1V and greater than or equal to VPP(min).
