2 / 19 page 2 TQ8105/TQ8106 PRELIMINARY DATA SHEET For additional information and latest specifications, see our website: www.triquint.com Figure 1. TQ8105 Block Diagram The combination of a thermally enhanced, 100-pin 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. TQ8105/TQ8106 diagnostics include: • Loss of Reference clock detector (LOR) output to indicate that the PLL Reference Clock is not toggling • Lock Indicator (RLOCK), which permits monitoring of the receiver clock frequency, flagging when the frequency drifts beyond approximately 500 ppm • Loss of Signal (LOS) detector output to indicate that the incoming data stream has no data transitions in 128-bit periods • ECL/PECL input (NSOL) to allow LOS from an O/E module to force the data stream to all zeroes, eliminating the need for external glue logic.
