Resources for 87946I-01
Description
The 87946I-01 is a low skew, ÷1, ÷2 Fanout Buffer. The 87946I-01 has one LVPECL clock input pair. The PCLK/nPCLK pair can accept LVPECL, CML, or SSTL input levels. The low impedance LVCMOS/LVTTL outputs are designed to drive 50Ω series or parallel terminated transmission lines. The effective fanout can be increased from 10 to 20 by utilizing the ability of the outputs to drive two series terminated lines. The divide select inputs, DIV_SELx, control the output frequency of each bank. The outputs can be utilized in the ÷1, ÷2 or a combination of ÷1 and ÷2 modes. The master reset input, MR/nOE, resets the internal frequency dividers and also controls the active and high impedance states of all outputs. The 87946I-01 is characterized at 3.3V core/3.3V output and 3.3V core/2.5V output. Guaranteed bank, output and part-to-part skew characteristics make the 87946I-01 ideal for those clock distribution applications demanding well defined performance and repeatability.
