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. PIN DESCRIPTIONS 8-pin SO package 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.

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. Cprobe 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: 5 pF Dt + C Dt Eff Where ∆t 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.: CEff = CLVDS + 1/2 Cprobe CLVDS + 1/2 Cprobe = 5 pF To correctly account for the effects of Cprobe, the following formula should be used: 2001 Jun 19 measured, 5 Philips Semiconductors Product data High-speed serial logic translators PTN3310/PTN3311 SO8: plastic small outline package; 8 leads; body width 3.9 mm 2001 Jun 19 6 SOT96-1 Philips Semiconductors Product data High-speed serial logic translators PTN3310/PTN3311 Data sheet status Data sheet status [1] Product status [2] Definitions Objective data Development This data sheet contains data from the objective specification for product development.
