Fig.32 Application diagram showing the OQ2541B configured for the STM16/OC48 mode (2488.32 Mbits/s) with
a positive supply voltage application (V
CC
= +5 V).
(1) All GND pins must be connected directly to V
CC
on the PCB plane of 5 V (pins 2, 5, 8, 11, 14, 17, 20, 23, 26, 29, 32, 35, 38, 41, 44 and 47).
(2) L1 = RF choke type Murata BLM21.
(3) The loop mode outputs are used as main outputs.
