Type
QT2032:
Gapped clock used for timing TDCC input.
Please see Section 7.3.8, “Transport Overhead Serial Interface,” on
page 48
QT2022:
Unused. Connect to GND.
Test data output (scan out when SCAN instruction written to TAP).)
Link Alarm Status Interrupt (LASI)
logic low = Interrupt asserted
logic high =No alarm interrupt asserted
See “Link Alarm Status Interrupt Pin (LASI)” on page 62.
With XFP=0, Active high laser driver enable as per XENPAK MSA
(see “Laser Driver Enable Pin (TXENABLE)” on page 69)
With XFP=1, drives TX_DIS input of XFP module
With XFP=0, low level indicates when the input signal applied at RXIP/N is
below a threshold which can be adjusted via the resistor connected to the
ITH_LOS pin
With XFP=1, drives P_DOWN/RST input of XFP module
EEPROM serial interface clock.
can be tristated via MDIO register 1.C024h.0 This is a bidirectional pin to
allow an external device to take control of the EEPROM I2C interface.
With XFP=1, drives the XFP module I2C interface.
EEPROM interface serial address/data.
With XFP=1, drives the XFP module I2C interface.
MDIO Interface serial data signal
External pullup to 1.2V required. Please see Section 9.5 on page 74 for
details.
With XFP=0, low power mode control input
0 = low power mode (only the MDIO, EEPROM and DOM functions are
active with an external reference clock applied at EREFCLKP/N)
1 = normal operating mode, default
With XFP=1, output to drive the MOD_DESEL input of an XFP module
LED driver and General Purpose I/O:
Can be configured as a LED driver output or as a GPIO via MDIO register
bits 1.D006h.2:0. The default configuration is as a LED driver.
As an input, its state is displayed in MDIO register bit 1.D006h.5; as an
output it can be driven by MDIO register bits 1.D006h.2:0 or other internal
status signals
(see Section 8.6 on page 70)
