The high data rate and exceptional signal fidelity is made possible with TriQuint's fully differential Source-Coupled FET Logic (SCFL) standard cells. The symmetrical switching characteristic inherent in differential logic results in low signal skew and crosstalk for maximum signal fidelity. The user can independently configure any switch output to any input, including an input chosen by another output. To configure the switch, the 4-bit output address (OA0..3) is decoded to enable the loading of the 4-bit input selection data (IA0..3) on the rising edge of the LOAD signal. The process is repeated until all desired connections are programmed. By bringing the CONFIGURE signal high, the contents of the Output Select Latches are transferred in parallel to a second row of 4-bit latches (R2), causing the switch reconfiguration. This double row architecture minimizes the time to completely reconfigure the switch since a new set of addresses can be loaded to the Output Select Latches (R1) while the switch is active (transmitting). At the time of reconfiguration, no data drop-out occurs for any output whose input connection does not change. Typical output waveform with all channels driven Features • >1.3 Gigabit/sec data rate • Non-blocking architecture • +200 ps delay match (one input to all outputs) • ECL-level data inputs/outputs; CMOS-level control inputs • Low crosstalk • Fully differential data path • Double row of output select latches minimizes reconfiguration time • Available in 132-pin leaded chip carrier For applications which do not require synchronous configuration of the switch, the LOAD and CONFIGURE inputs may be tied together.

Data is provided for both time and voltage domains of the differential DIN0 to DOUT0 data path for various data rates. An interference pattern was applied to all other inputs in parallel to induce worst-case cross talk. For the time domain, Peak-to-Peak Jitter was measured at the eye crossing. An error-free percentage value was computed using the following formula: (Data_Period - PPJitter) x 100 / Data_Period Voltage values are referenced to an initial inner eye measurement at 400 MBs.
