V23815-U1306-MXXX Datasheet, PDF (5/9 Pages) Infineon Technologies AG – Parallel Optical Link: PAROLI T X AC, 1.6 Gbit/s

DESCRIPTION
Receiver V23815-U1306-M130
The PAROLI receiver module converts parallel optical input
signals into parallel electrical output signals. The optical signals
received are converted into voltage signals by PIN diodes,
transimpedance amplifiers, and gain amplifiers. All output data
signals are Low Voltage Differential Signals (LVDS). The data
rate is 250-1600 Mbit/s for each channel. Optical input data
should be DC balanced within 144 bits. The maximum time
interval of consecutive 0’s and 1’s (run length) should not
exceed 72 bits. This will ensure that the output jitter values
given for the transmitter and receiver in this data sheet will be
met. Otherwise, jitter values might be exceeded.
Additional Signal Detect outputs (SD1 active high / SD12 active
low) show whether an optical AC input signal is present at data
input 1 and/or 12. The signal detect circuit can be disabled with
a logic low at ENSD. The disabled signal detect circuit will
permanently generate an active level at Signal Detect outputs,
even if there is insufficient signal input. This could be used for
test purposes.
A logic low at LVDS Output Enable sets all data outputs to logic
low. SD outputs will not be effected.
All nondata signals have LVCMOS levels. Transmission delay of
the PAROLI system is at a maximum 1 µs for the transmitter,
1 µs for the receiver and approximately 5 ns per meter for the
fiber optic cable.
