FEATURES

  • Meets LVDS EIA-644 and PECL standards
  • 2 pin-for-pin replacement input/output choices: – LVDS in, PECL out (PTN3310) – PECL in, LVDS out (PTN3311)
  • Single +3.3 V supply voltage operation
  • Available in 8-pin SO package
  • Maximum throughput data rate of 800 Mbps typical

APPLICATIONS

  • High-speed networking and telecom applications – ATM – SONET/SDH – Switches – Routers – Add-drop multiplexers GENERAL DESCRIPTION The High-Speed Serial Logic Translator provides a point solution that addresses the various interface logic requirements of Optical Transceiver Modules. The product offers a compact translation between LVDS and PECL high speed serial data lines. This provides the end users a simple way to mix or match Optical Transceiver ICs from various vendors to maximize desired performance and reduces the need to redesign interfaces to accommodate new Optical Transceiver ICs. The High-Speed Serial Logic Translator comes in two translation choices to allow mixing LVDS and PECL input/outputs. The product is offered in a small, convenient, 8-pin package. Figure 1 shows the High-Speed Serial Logic Translator Device in a typical high speed optical module application. Figure 2 shows the circuit block diagrams.

According to the TIA-EIA-644 Standard, the maximum lumped capacitance test load should be 5 pF. However, by using probes or cables to observe the signal, additional capacitance is added, which has an effect on the rise and fall times. C probe represents any capacitance caused by the use of probes or cables. Assuming balanced loading and balanced output drivers, the total effective capacitance seen by the part is: C Eff = CLVDS + 1/2 Cprobe To correctly account for the effects of Cprobe, the following formula should be used: /C0068t/C0043 5p F C Eff /C0068tmeasured, Where Δt is the 20%–80% rise/fall time. To avoid the use of additional calculation of the measured results, a different approach could be taken; however, the value of Cprobe has to be known in advance. In that case, the value of CLVDS can be chosen such that the sum of the capacitances equals 5 pF, i.e.: C LVDS + 1/2 Cprobe = 5 pF
