Low-speed Signaling
Low-speed signaling is based on low-voltage TTL (LVTTL) operating at a nominal
voltage of 3.3 V.
SCL/SDA: Two wire Serial interface clock and data line. Hosts should use a pull-up
resistor connected to Vcc 3.3 V on the two-wire interface SCL (clock), SDA (data),
and all low-speed outputs.
Mod_NR: Output pin. High indicates that the module has detected a condition
that renders Tx and or Rx data invalid.
Mod_DeSel: Input pin. When held low by the host the module responds to two-
wire serial communication commands. When high the module does not respond
to or acknowledge any two-wire interface communication from the host.
Interrupt: Output pin. Low indicates possible module operational fault or a status
critical to the host system.
TX_DIS: Input pin. High indicates the transmitter output is turned off.
Mod_ABS: Output pin. High indicates the XFP module is absent; low indicates the
XFP module is inserted.
RX_LOS: Output pin. High indicates insufficient optical power for reliable signal
reception is received.
P_Down/RST: Multifunction input pin. The module can be powered down or
reset by pulling the low-speed P-Down pin high. In power-down mode, no data is
transmitted on the optical Tx or the electrical Rx path. The reset pulse is generated
on the falling edge of the P-Down signal. Following reset, the internal PLLs must
reacquire lock and will temporarily indicate a Mod_NR failure until the PLLs
reacquire lock.
Section 2
Recommended MSA connections to the transceiver are shown in Figure 2 on page 5.
Power supply filtering is recommended. To limit wideband noise power, the host
system and module shall each meet a maximum of 2% peak-to-peak noise when
measured with a 1 MHz low-pass filter. In addition, the host system and the
module shall each meet a maximum of 3% peak-to-peak noise when measured
with a filter from 1 – 10 MHz.
