3.0 Functional Description
he ZL40219 is an LVDS clock fanout buffer with eight output clock drivers capable of operating at frequencies up to
750MHz.
The ZL40219 provides an internal input termination network for DC and AC coupled inputs; optional input biasing
for AC coupled inputs is also provided. The ZL40219 can accept DC coupled LVPECL or LVDS and AC coupled
LVPECL and LVDS input signals, AC coupled CML or HCSL input signals, and single ended signals. A pin
compatible device with external termination is also available.
The ZL40219 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 device has a differential input equipped with two on-chip 50 Ohm termination resistors arranged in series with a
center tap. The input can accept many differential and single-ended signals with AC or DC coupling as appropriate.
A control pin is available to enable internal biasing for AC coupled inputs. A block diagram of the input stage is in
Figure 3.

This following figures give the components values and configuration for the various circuits compatible with the
input stage and the use of the Vt and ctrl pins in each case.
In the following diagrams where the ctrl pin is logically one and the Vt pin is not connected, the Vt pin can be
instead connected to VDD with a capacitor. A capacitor can also help in Figure 4 between Vt and VDD. This
capacitor will minimize the noise at the point between the two internal termination resistors and improve the overall
performance of the device.

3.3 Device Additive Jitter
The ZL40219 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 ZL40219 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 ZL40219 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.

3.4 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 ZL40219 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 regulation,
recommended power supply filtering, and good PCB layout all work together to minimize the 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 •.

10 µF capacitors should be size 0603 or size 0805 X5R or X7R ceramic, 6.3 V minimum rating
0.1 µF capacitors should be size 0402 X5R ceramic, 6.3 V minimum rating
Capacitors should be placed next to the connected device power pins
A 0.15 ohm resistor is recommended

* 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.
