• Manufacturer: INFINEON [Infineon Technologies AG]

APPLICATION NOTE
Single Mode 622 MBd ATM 1x9 Transceiver, AC/AC TTL and AC/AC PECL Versions
Values of R1/2/3/4 may vary as long as proper 50
to V
ing is required for good EMI performance. Use short tracks
from the inductor L1/L2 to the module V
application notes for electrical interfacing are available upon
request. Ask for Appnote 82.

We strongly recommend a V
getting good EMI performance.
The transceiver contains an automatic shutdown circuit. Reset
is only possible if the power is turned off, and then on again.
