Low-Speed Signaling
Low-speed signaling is based on low voltage transistor-transistor logic (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. When asserted 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. When low, indicates possible module operational fault or a
status critical to the host system.
TX_DIS—Input pin. When asserted high, the transmitter output is turned off.
Mod_ABS—Output pin. Asserted high when the XFP module is absent and is pulled
low when the XFP module is inserted.
RX_LOS—Output pin. Asserted high when 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.
