DESCRIPTION
The PL611-30 is a low-cost general purpose frequency synthesizer and a member of PhaseLink’s Factory
Programmable ‘Quick Turn Clock (QTC)’ family. PhaseLink’s PL611-30 product family can generate any output
frequency up to 400MHz from fundamental crystal input between 10MHz - 30MHz, a 3rd overtone crystal of up to
75MHz (3.3V Only) or a Reference Clock from 1MHz to 200MHz. The PL611-30 produces complementary
LVCMOS outputs to support LVPECL, LVDS, and LVCMOS inputs.

TERMINATING COMPLEMENTARY LVCMOS OUTPUTS
Figure 1 below describes how to terminate the complementary LVCMOS outputs of PhaseLink’s PL611-30
Programmable QTC clock for use with LVPECL or LVDS inputs.
The unique feature of complementary LVCMOS outputs allows great flexibility for board designers. By
standardizing on one termination scheme you can use the PL611-30 for all your LVDS and LVPECL clock
requirements up to 400MHz.

Notes:
Place R1 as close to the LVCMOS outputs as
possible.
R1 = 130 Ohm
R2 = 82 Ohm
R3 = 130 Ohm
Place R2 and R3 as close to the LVPECL/LVDS
inputs as possible.
R1 = 360 Ohm
R2 = 130 Ohm
R3 = 82 Ohm
Figure 1
The above layout allows the PL611-30 to drive either LVPECL or LVDS inputs by simply changing the value of R1.
