5.1. Narrowband versus Wideband Operation
This document describes five evaluation boards: Si5316, Si5319, Si5322/23, Si5324, and Si5325/26. The Si5316
and Si5322/23 evaluation boards are for pin controlled clock parts and the Si5319, Si5324, and Si5325/26 are for
clock parts that are to be controlled by an MCU over a serial port. The Si5316-EVB, Si5319-EVB, and Si5324-EVB
support only one part, while the two other boards each support two parts: one that is wideband (the Si5322 and the
Si5325) and one that is narrowband (the Si5323 and the Si5326). The narrowband parts are both capable of
operating in the wideband mode, so evaluation of the wideband parts can be done by using a narrowband part in
wideband mode. As such, these evaluation boards are only populated with narrowband parts.
The Si5324-EVB is a special case because the Si5324 has a lower loop bandwidth and does not support wideband
operation. Because of the lower loop bandwidth, the lock times are significantly increased and the Si5324 will be
more sensitive to XA-XB reference crystal temperature changes. For this reason, a 20 ppm crystal is used on the
SI5324-EVB. It should be noted that the 20 ppm crystal is used for its temperature stability, not its absolute
accuracy. If the crystal will undergo significant changes in temperature, it is suggested that the crystal be thermally
insulated by covering it with foam tape or some other means.
To evaluate Si5322 device operation using the Si5322/23-EVB, the RATE[1:0] pins must be set to LL using the
jumpers provided. To evaluate Si5325 device operation using the Si5325/26-EVB, the Precision Clock EVB
Software should be configured for wideband mode. For details, see the Precision Clock EVB Software
documentation.
