6.0 Applications
This section contains ZL30102 application specific details for power supply decoupling, reset operation, clock and
crystal operation.
6.1 Power Supply Decoupling
Jitter levels on the ZL30102 output clocks may increase if the device is exposed to excessive noise on its power
pins. For optimal jitter performance, the ZL30102 device should be isolated from noise on power planes connected
to its 3.3 V and 1.8 V supply pins. For recommended common layout practices, refer to Zarlink Application Note
ZLAN-178.
6.2 Master Clock
The ZL30102 can use either a clock or crystal as the master timing source. Zarlink application note ZLAN-68 lists a
number of applicable oscillators and crystals that can be used with the ZL30102.
6.2.1 Clock Oscillator
When selecting a clock oscillator, numerous parameters must be considered. This includes absolute frequency,
frequency change over temperature, output rise and fall times, output levels, duty cycle and phase noise.
The output clock should be connected directly (not AC coupled) to the OSCi input of the ZL30102, and the OSCo
output should be left open as shown in Figure 19.
