FEATURES
• The PM5307 TBS-9953 switches timeslots (down to an STS-1 granularity) from/to the line side interface to/from a system side working (W), protection (P), and optionally an auxiliary (A) interface.
• 4 sets of 16 port serial links:
• 2 sets of 16 x 777.6 Mbit/s links (8B/10B encoded Serial TelecomBus).
• 2 set of configurable 16 x 777.6 Mbit/s or 16 x 2.488 Gbit/s (SONET/SDH scrambled).
• Typical applications (line to system interfaces):
• 16 x 777.6 Mbit/s to 3 x 16 x 777.6 Mbit/s (W,P,A)
• 16 x 777.6 Mbit/s to 4x4x2.488 Gbit/s (W,P,A1,A2)
• 2 x (16 x 777.6) Mbit/s to 2 x (2 x 4 x 2.488) Gbit/s (W, P) - Dual TBS
• 4 x 2.488 Gbit/s to 3 x 4 x 2.488 Gbit/s (W,P,A)
• Supports redundant working/protection time-space-time switch fabrics, including the PM5372 TSE and PM5374 TSE-160 devices.
• Supports STS-192c/STM-64c, STS- 48c/STM-16c, STS-12c/STM-4c, and STS-3c/STM-1c traffic on the interface.
• Supports through-traffic, drop-traffic and protection switching in UPSR, 2-fiber BLSR and 4-fiber BLSR applications.
• Provides per link concatenated SONET PRBS generation/ monitoring for outgoing/ incoming LVDS data link for off-line link verification. 777.6 Mbit/s links can carry an STS-12c PRBS stream. 2.488 Gbit/s links can carry an STS-48c PRBS stream.
• Option to perform in-service link verification by checking and/or overwriting the Z2 byte of each constituent STS-1/STM-0 frame with a unique software programmable byte and its complement.
• Provides pins to coordinate updating of the connection map of the time-slot interchange blocks in the local device, peer PM5307 TBS-9953 devices, and companion PM5374 TSE-160 or PM5372 TSE devices.
• Provides two independent time domains for frame alignment purposes. The time domains for each link interface are selectable through the software interface.
• Driven by a 155.52 MHz reference clock.
• Implemented in 1.8 V core and 3.3 V I/O, 0.18 µm CMOS and packaged in a 1152 ball FCBGA.
• Provides a standard IEEE 1149.1 JTAG port.
