... 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 ...

... JEDEC, metric, plastic package, the low-power dissipation of the device, and the wide case- temperature range permits operation without a heat sink in most designs. The TQ8106 uses the same pinout as the TQ8105 and is compatible with it. The TQ8105/TQ8106 provides comprehensive, integrated, loopback functionality and enhanced line and reference clock diagnostics required of SONET/ SDH systems, minimizing additional external circuitry ...

... Clock Source Mode 011 (see Table 3). Framer The TQ8105 and TQ8106 provide a clean interface to devices from PMC-Sierra and others. The Out-of-Frame (OOF) input is a state (level)-initiated event, rather than the edge-triggered event found on TriQuint’s first- generation TQ8101 transceiver ...

... The LOR (Loss Of Reference) output goes high when the reference clock is absent. Note that this signal is not latched and is only high when the reference clock is missing. A reference clock is required for the TQ8106 CDR to function correctly. The NSOL (Loss-of-signal input, active low, PECL/ECL level) input allows the receiver to force zeroes onto the demux outputs ...

... These design notes are provided to assist the circuit designer in achieving the highest possible performance while reducing design time. Unless noted otherwise, references to the TQ8105 apply equally to the TQ8106. Interfacing to PMC-Sierra Devices The transmit timing of the TQ8105 is such that the PMC-Sierra byte outputs (POUT(0:7)) may be directly connected to the TQ8105 mux inputs (MXD(0:7)) ...
