Functional Description
Providing two banks of four outputs, the PI6C2308A is a 3.3V zero-
delay buffer designed to distribute clock signals in applications
including PC, workstation, datacom, telecom, and high-performance
systems. Each bank of four outputs can be controlled by the select
inputs as shown in the Select Input Decoding Table.
The PI6C2308A provides 8 copies of a clock signal that has 150ps
phase error compared to a reference clock. The skew between the
output clock signals for PI6C2308A is less than 200ps. When there
are no rising edges on the REF input, the PI6C2308A enters a power
down state. In this mode, the PLL is off and all outputs are Hi-Z. This
results in less than 12
μ
A of current draw. The Select Input Decoding
table shows additional examples when the PLL shuts down. The
PI6C2308A configuration table shows all available devices.
The base part, PI6C2308A-1, provides output clocks in sync with
a reference clock. With faster rise and fall times, the PI6C2308A-1H
is the high-drive version of the PI6C2308A-1. Depending on which
output drives the feedback pin, PI6C2308A-2 provides 2X and 1X
clock signals on each output bank. The PI6C2308A-3 allows the user
to obtain 4X and 2X frequencies on the outputs. The PI6C2308A-4
provides 2X clock signals on all outputs. PI6C2308A (-1, -2, -3, -4)
allows bank B to be Hi-Z when all output clocks are not required.The
PI6C2308A-6 allows bank B to switch from Reference clock to half
of the frequency of Reference clock using the control inputs S1 and
S2 if Bank A is connected to feedback FBK. In addition, using the
control inputs S1 and S2, the PI6C2308A-6 allows bank A to switch
from Reference clock to 2X the frequency of Reference clock if Bank
B is connected to feedback FBK. For testing purposes, the select
inputs connect the input clock directly to outputs.
