These four devices are high frequency oscillator gain stages supporting both LVPECL or LVDS on the high gain outputs in 3.3-V or 2.5-V systems. Additionally, provides the option of both single-ended input (PECL levels on the SN65LVx18) and fully differential inputs on the SN65LVx19.

The SN65LVx18 provides the user a Gain Control (GC) for controlling theQoutput from 300 mV to 860 mV either by leaving it open (NC), grounded, or tied to VCC. (When left open, theQoutput defaults to 575 mV.) TheQon the SN65LVx19 defaults to 575 mV as well.

Both devices provide a voltage reference (VBB) of typically 1.35 V below VCCfor use in receiving single-ended PECL input signals. When not used, VBBshould be unconnected or open.Read more
