OPERATION
DIGITAL DESYNCHRONIZER PLL CONNECTIONS
The following diagram shows the external connections required for each of the three digital desynchronizers,
where n defines the channels 1 through 3.
Traces should be kept as short as possible. Place the external components as close as possible to the associ-
ated device leads. Please refer to AN-537 (TXC-03453-AN1) for additional recommendations for board layout
design. This Application Note is available on the TL3M page of the TranSwitch web site, www.transwitch.com.
TRANSMIT AND RECEIVE SYNTHESIZER CONNECTIONS
The following diagram shows the external connections required for the two synthesizer circuits.
Traces should be kept as short as possible. Place the external components as close as possible to the associ-
ated device leads. Please refer to AN-537 (TXC-03453-AN1) for additional recommendations for board layout
design. This Application Note is available on the TL3M page of the TranSwitch web site, www.transwitch.com.
* Preferred: 1.0 F, 10V ceramic X7R 1206.
