ESCRIPTION
The ICS87949I is a low skew, ÷1, ÷2 Clock Generator.
The ICS87949I has selectable single ended clock or
LVPECL clock inputs. The single ended clock input
accepts LVCMOS or LVTTL input levels. The PCLK, nPCLK
pair can accept LVPECL, CML, or SSTL input levels. The
low impedance LVCMOS outputs are designed to drive 50Ω
series or parallel terminated transmission lines.The
effective fanout can be increased from 15 to 30 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 ICS87949I is characterized at 3.3V core/3.3V output.
Guaranteed output and part-to-part skew characteristics make
the ICS87949I ideal for those clock distribution applications
demanding well defined performance and repeatability.
