QT2032:
Transmit data communication channel input for both section and line
SONET overhead data; clocked in using the TDCC_CLK output. Please see
Section 7.3.8, “Transport Overhead Serial Interface,” on page 48.
QT2022:
Unused. Connect to GND.
QT2032:
LAN/WAN Mode select
0 = WAN mode enabled
1 = LAN mode enabled (default)
When LANMODE = 1, the chip will not operate in WAN mode and access to
all WIS registers is disabled. When LANMODE = 0, the chip will default to
WAN mode operation but can be set to operate in LAN mode by setting
MDIO register bit 2.7.0 to 0.
QT2022:
Unused. Leave unconnected.
QT2032:
SREFCLK frequency selection
0 = 155.52 MHz (default)
1 = 622.08 MHz
QT2022:
Unused. Leave unconnected.
QT2032:
VCXO frequency selection
0 = 155.52 MHz (default)
1 = 622.08 MHz
QT2022:
Unused. Leave unconnected.
QT2032:
VCXO control loop enable pin. A low-level configures the chip to implement
a PLL using an external VCXO - see description in Section 6.2.4, “VCXO
PLL,” on page 32.
0 = enabled
1 = disabled (default)
QT2022:
Unused. Leave unconnected.
QT2032:
Input to indicate that the VCXO is the only reference clock available (i.e.
there is no SREFCLK input - so in non-linetiming mode, there is no
switchover to it)
0 = there is a SREFCLK input in WAN mode (default)
1 = there is no SREFCLK input in WAN mode (i.e. VCXO alone. Also set
REFSEL622 = VCXOSEL622)
QT2022:
Unused. Leave unconnected.
