SDO/(E3_Ch0)
I/O
Serial Data Output from the Microprocessor Serial Interface/
E3_Mode Select - Channel 0:
The function of this pin depends upon the mode of operation.
HOST Mode Operation - Serial Data Output for the Microprocessor
Serial Interface:
This pin serially outputs the contents of the specified Command Register
during Read Operations. The data on this pin is updated on the falling
edge of the SClk input signal. This pin is tri-stated upon completion of
data transfer.
Hardware Mode Operation - E3 Mode Select - Channel 0:
This input pin is used to configure Channel 0 to operate in the E3 or
STS-1/DS3 Modes. Setting this input pin to "High" configures Channel 0
to operate in the E3 Mode. Setting this input pin to "Low" configures
Channel 0 to operate in either the DS3 or STS-1 Modes, depending
upon the state of the STS-1/DS3_Ch0 input pin.
N
OTE
:
This pin is internally pulled “Low” when XRT73L04 is in the Hard-
ware Mode.
73
STS1/DS3_Ch0
I
STS-1/DS3 Select Input - Channel 0:
“High” for STS-1 and “Low” for DS3 Operation.
The XRT73L04 ignores this pin if the E3_Ch0 pin is set to "1".
This input pin is ignored if the XRT73L04 is operating in the HOST Mode.
N
OTE
:
This pin should be tied to GND if the XRT73L04 is going to be
operating in the HOST Mode, (internally pulled-down).
74
ICT
I
In-Circuit Test Input
:
Setting this pin "Low" causes all digital and analog outputs to go into a
high-impedance state to allow for in-circuit testing. This pin should be
set to "High" for normal operation.
This pin is internally pulled "High".
75
LOSTHR
I
Loss of Signal Threshold Control
:
Forcing the LOSTHR pin to GND or VDD provides two settings. This pin
must be set to a “High” or “Low” level upon power up and should not be
changed during operation.
This pin is only applicable during DS3 or STS-1 operations.
76
LLB0
I
Local Loop-back - Channel 0
:
This input pin along with RLB0 dictates which Loop-Back mode Channel
0 is operating in.
A "High" on this pin with RLB0 set to "Low" configures Channel 0 to
operate in the Analog Local Loop-Back Mode.
A "High" on this pin with RLB0 also being set to "High" configures Chan-
nel 0 to operate in the Digital Local Loop-Back Mode.
N
OTE
:
This pin is ignored and should be tied to GND if the XRT73L04 is
going to be operating in the HOST Mode.
77
RLB0
I
Remote Loop-Back - Channel 0:
This input pin in conjunction with LLB0 dictates which Loop-Back mode
Channel 0 is operating in.
A "High" on this pin with LLB0 being set to "Low" configures Channel 0 to
operate in the Remote Loop-Back Mode.
A "High" on this pin with LLB0 also being set to "High" configures Chan-
nel 0 to operate in the Digital Local Loop-Back Mode.
N
OTE
:
This pin is ignored and should be tied to GND if the XRT73L04 is
going to be operating in the HOST Mode.
