5.3.4 Low Voltage PECL (LVPECL) Interface Example
Figure 5-16. LVPECL Interface
29600-DSH-001-B
Note(s):
1. The 100 ohm resistor is built in the CX29600 for LRxData+ and LRxData- termination.
2. The LTxData+ and LTxData- outputs are internally biased and therefore do not require external bias resistors.
3. The termination resistors on the LSigDet input are necessary only for transceivers with a PECL level signal detect (SD) output.
