QUAD T1/E1 LINE INTERFACE DEVICE
PMC-Sierra has verified the operation of the XPLS functional block with the
following 1:1.36 transformers:
• Pulse Engineering PE64937 (1:1.36)
• Pulse Engineering PE65340 (1:1.36) (for extended temperature range)
• BH Electronics 500-1776 (1:1.36)
Many manufacturers produce dual transformers containing the1:2 CT and 1:1.36
transformers necessary for the receiver and transmitter circuits. PMC-Sierra has
verified the operation of XPLS and RSLC with the following dual parts:
• Pulse Engineering PE64952
• Pulse Engineering PE65774 (for extended temperature range)
• BH Electronics500-1777
9.12 IEEE P1149.1 JTAGTest Access Port
The IEEE P1149.1 JTAG Test Access Port block provides JTAG support for
boundary scan. The standard JTAG EXTEST, SAMPLE, BYPASS, IDCODE and
STCTEST instructions are supported. The QDSX identification code is
043140CD in hexadecimal format, shifted least significant bit first.
9.13 Microprocessor Interface
The microprocessor interface block provides normal and test mode registers, and
the logic required to connect to the microprocessor interface. The normal mode
registers are required for normal operation, and test mode registers are used to
enhance the testability of the QDSX. The register set is accessed as follows:
