• Manufacturer Part Number: afbr-1012
• Description: Fiber Optic Transmitter And Receiver For 50 Mbaud Most?
• Manufacturer: Avago Technologies

AFBR-1012 (Transmitter)
DC Characteristics
Notes:
1. The current through the LED and therefore the optical output power and overall power consumption depends on the settings of R
2. If the transmitter is in full power mode it is switched OFF 1ms (max) after Tx DATA is low. If the transmitter is in low power mode it is switched ON
AC Electrical Characteristics
Optical Signal Characteristics 45.158Mbaud (44.1kHz)
(22.5 MBit/s MOST Data, V
Notes:
1. Average value when transmitting modulated light @signal timing parameters. The output power coupled into plastic fi ber Popt is measured with
2. Average value when signal on Tx_Data is low
3. The electrical input signal has to fulfi ll the following requirements: t
4. Characterized with Avago Characterization Boards
5. Limits for 2UI are 42.2 … 46.4ns and for 3UI they are 64.3 … 68.5ns.
6. Top and Base level measured at least over 10UIs.
