Broadcom 25 MHz LVDS Clock
ICS556-01
Quartz Crystal
The ICS556-01 25 MHz LVDS Clock utilizes an
external crystal to generate a low phase noise output.
To assure the best system performance and reliability,
a crystal device with the recommended parameters
(shown below) must be used, and the layout guidelines
discussed in the following section shown must be
followed.
The frequency of oscillation of a quartz crystal is
determined by its “cut” and by the load capacitors
connected to it. The crystal specified for use with the
ICS556-01 is designed to have zero frequency error
when the total of on-chip plus stray capacitance is 5 pF.
Recommended Crystal Parameters:
Initial Accuracy of 25°C
±20 ppm
Temperature Stability

Load Capacitance5 pf
Shunt Capacitance, C02 pF Max
Equivalent Series Resistance80

The external crystal must be connected as close to the
chip as possible and should be on the same side of the
PCB as the ICS556-01. There should be no via’s
between the crystal pins and the X1 and X2 device
pins. There should be no signal traces underneath or
close to the crystal.
The value (in pF) of these crystal caps should equal
(CL - 12 pF)*2. In this equation, CL =crystal load
capacitance in pF. Example: or a crystal with a 16 pF
load capacitance, each crystal capacitor would be 8 pF
[(16-12) x 2] = 8.
Absolute Maximum Ratings
Stresses above the ratings listed below can cause permanent damage to the ICS556-01. These ratings,
which are standard values for ICS commercially rated parts, are stress ratings only. Functional operation of
the device at these or any other conditions above those indicated in the operational sections of the
specifications is not implied. Exposure to absolute maximum rating conditions for extended periods can
affect product reliability. Electrical parameters are guaranteed only over the recommended operating
temperature range.
