Product Description
The PI6C487016 is a low skew. 1:16 LVCMOS/LVTTL Clock
Driver. The device has 4 banks of 4 outputs and each bank can
be independently selected for ÷1 or ÷2 frequency operation.
Each bank also has its own power supply pins so that the banks
can operate at the following different voltage levels: 3.3V, 2.5V,
and 1.8V. The low impedance LVCMOS/LVTTL outputs are
designed to drive 50 series or parallel terminated transmission
lines.
The divide select inputs, SELA:SELD, control the output fre-
quency of each bank with either ÷1 or ÷2 frequency operation.
The bank enable inputs, ENA:END, support enabling and dis-
abling each bank of outputs individually. The outputs synchro-
nized when enabling or disabling the clock outputs. The master
reset input nMR/OE, resets the ÷1/÷2 flip flops and also controls
the active and high impedance states of all outputs.
The PI6C487016 is characterized to operate with the core at
3.3V and the output banks at 3.3V, 2.5V or 1.8V.
