• MUX board includes PLL circuitry for clean 622 MHz reference clock
• DMUX board includes level detect and true system LOS
• Eliminates need for 9.9532 b/s board design
• Multi-pin footprint provided for 622 Mb/s Clock and Data LVDS interface
• SMP Compatible connectors for 9.9532 b/s I/O
Description
The MTC11207A and MTC11224A are miniature printed circuit board subassemblies, referred to as boardlets, which contain the MTC1207A 9.953 b/s MUX/CMU and the MTC1224A CDR/DMUX respectively. Each boardlet contains all external circuitry necessary to allow the MUX and DMUX to function properly when interfaced with the 622 MHz LVDS clock and data signals originating on the main system board.
The 622 MHz clock and data signals are interfaced to the system board using a set of pad arrays that are compatible with a commercially available surface mount multi-pin connector. The boardlets eliminate complicated and time consuming 9.953 b/s PCB design since all 9.953 b/s signal traces are self contained on each boardlet. Their small outline and simplified interfacing requirements makes the boardlets idealy suited for use in SONET OC-192 or SDH STM-64 telecommunications equipment.
