5.2. Block Diagram
Figure 2 is a block diagram of the evaluation board. The MCU communicates to the host PC over a USB
connection. The MCU controls and monitors the Si532x through the CPLD. The CPLD, among other tasks,
translates the signals at the MCU voltage level of 3.3 V to the Si532x's voltage level, which is nominally 3.3, 2.5, or
1.8 V. The user has access to all of the Si532x's pins using the various jumper settings as well as through the host
PC via the MCU and CPLD.

5.3. Si532x Input and Output Clocks
The Si532x has two differential inputs that are ac terminated to 50
 and then ac coupled to the part. Single-ended
operation can be implemented by simply not connecting to one of the two of the differential pairs bypassing the
unused input to ground with a capacitor. When operating with clock inputs of 1 MHz or less in frequency, the
appropriate dc blocking capacitors (C39, C41, C34, and C36) located on the bottom of the board should be
replaced with 0
 resistors. The reason for this is that the capacitive reactance of the ac coupling capacitors
becomes significant at low frequencies. It is also important that the CKIN signal meet the minimum rise time of
11 ns (CKNtrf) even though the input frequency is low.
The two clock outputs (one for the Si5316-EVB and Si5319-EVB) are all differential, ac-coupled and configured for
driving 50
 transmission lines. When using single ended outputs, it is important that the unused half of the
output be terminated.
Two jumpers are provided to assist in monitoring the Si532x power: When R27 is removed, J20 can be used to
measure the device current. J12 can be used at any time to monitor the supply voltage at the device.
The Si5316, Si5319, Si5323, Si5326, and Si5327 require that an external reference be provided to enable the
devices to operate as narrowband jitter attenuators with loop bandwidths as low as 60 Hz (4 Hz for the Si5324 and
Si5327). The external reference source can be either a crystal, a standalone oscillator or some other clock source.
The range of acceptable reference frequencies is described in the Any-Frequency Precision Clocks Family
Reference Manual (Si53xxRM.pdf). The EVBs are shipped with a third overtone 114.285 MHz crystal that is used
in the majority of applications. J1 and J2 are used when the Si532x is to be configured in narrowband mode with an
external reference oscillator (i.e. without using the 114.285 MHz crystal). The Si5327-EVB is shipped with a
40 MHz fundamental mode crystal.
The RATE pins should also be configured for the desired mode, using the jumper plugs at J9 (see Table 6).
For unused inputs and outputs, please refer to the Any-Frequency Precision Clocks Family Reference Manual
(Si53xxRM.pdf).
