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. 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 sig-
nal 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 trans-
mitted 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 PLL’s must reacquire
lock and will temporarily indicate a Mod_NR failure until the PLL’s reacquire lock.

Recommended MSA connections to the JDSU 10 Gbps 1550 nm multiprotocol
XFP optical transceiver are shown in Figure 2 on page 5.
Power supply filtering is recommended for the JDSU 10 Gbps 1550 nm multipro-
tocol XFP optical transceiver. To limit wide band noise power, the host system and
module shall each meet a maximum of 2 percent peak-to-peak noise when mea-
sured with a 1 MHz low pass filter. In addition, the host system and the module
shall each meet a maximum of 3 percent peak-to-peak noise when measured with
a filter from 1 MHz–10 MHz.
