Data Sheet
Functional Description
The ZL40218 is an LVDS clock fanout buffer with eight identical output clock drivers capable of operating at
frequencies up to 750MHz.
Inputs to the ZL40218 are externally terminated to allow use of precision termination components and to allow full
flexibility of input termination. The ZL40218 can accept DC or AC coupled LVPECL, LVDS, CML or HCSL input
signals; single ended input signals can also be accepted. A pin compatible device with internal termination is also
available.
The ZL40218 is designed to fan out low-jitter reference clocks for wired or optical communications applications
while adding minimal jitter to the clock signal. An internal linear power supply regulator and bulk capacitors
minimize additive jitter due to power supply noise. The device operates from 2.5V+/-5% or 3.3V+/-5% supply. Its
operation is guaranteed over the industrial temperature range -40°C to +85°C.
The device block diagram is shown in Figure 1; its operation is described in the following sections.
3.1
Clock Inputs
The ZL40218 is adaptable to support different types of differential and singled-ened input signals depending on the
passive components used in the input termination. The application diagrams in the following figures allow the
ZL40218 to accept LVPECL, LVDS, CML, HCSL and single-ended inputs.

Device Additive Jitter
The ZL40218 clock fanout buffer is not intended to filter clock jitter. The jitter performance of this type of device is
characterized by its additive jitter. Additive jitter is the jitter the device would add to a hypothetical jitter-free clock as
it passes through the device. The additive jitter of the ZL40218 is random and as such it is not correlated to the jitter
of the input clock signal.
The square of the resultant random RMS jitter at the output of the ZL40218 is equal to the sum of the squares of the
various random RMS jitter sources including: input clock jitter; additive jitter of the buffer; and additive jitter due to
power supply noise. There may be additional deterministic jitter sources, but they are not shown in Figure 17.

Power Supply
This device operates employing either a 2.5V supply or 3.3V supply.
3.4.1
Sensitivity to power supply noise
Power supply noise from sources such as switching power supplies and high-power digital components such as
FPGAs can induce additive jitter on clock buffer outputs. The ZL40218 is equipped with an on-chip linear power
regulator and on-chip bulk capacitors to minimize additive jitter due to power supply noise. The on-chip measures in
combination with the simple recommended power supply filtering and PCB layout are effective at minimizing
additive jitter from power supply noise.
3.4.2
Power supply filtering
Jitter levels may increase when noise is present on the power pins. For optimal jitter performance, the device
should be isolated from the power planes connected to its power supply pins as shown in Figure .

Notes
* The values in this table are the additive periodic jitter caused by an interfering tone typically caused by a switching power supply. For this test,
measurements were taken over the full temperature and voltage range for VDD = 3.3 V. The magnitude of the interfering tone is measured at the
DUT.
