44 MHz) • External RC-based loop filters • Integrated loopbacks with enhanced line and reference clock diagnostics • Direct-coupled standard, PECL, high-speed I/O with ECL option • Clean TTL interface to PMC-Sierra devices • 100-pin 14x14 mm JEDEC plastic package • +5V-only supply for PECL I/O (–5.
2V required for ECL I/O option) • –40 to +125°C case operating temperature The TQ8105/TQ8106 are SONET/SDH transceivers that integrate multiplexing, demultiplexing, SONET/SDH framing, clock-synthesis PLL, and enhanced line and clock diagnostic functions into a single monolithic device.
The TQ8106 is a pin-compatible upgrade of the TQ8105 that includes a Clock and Data Recovery (CDR) function.
The TQ8105 and TQ8106 allow maximum flexibility in the selection of internal/external Clock and Data Recovery, Opto-Electronic (O/E) Module, and Reference Clock Sources.
On-chip PLLs use external RC-based loop filters to allow custom tailoring of loop response and support the wide range of reference clock frequencies found in SONET/SDH/ATM systems.
For transmit clock synthesis or for CDR, the PLLs exceed ANSI, Bellcore, and ITU jitter specifications for systems when combined with industry-typical O/E devices such as Sumitomo, AT&T, H...
