Description
www.ti.com SN65LVDS18, SN65LVP18 SN65LVDS19, SN65LVP19 SLLS624B – SEPTEMBER 2004 – REVISED NOVEMBER 2005 2.5-V/3.3-V OSCILLATOR GAIN STAGE/BUFFERS FEATURES • Low-Voltage PECL Input and Low-Voltage PECL or LVDS Outputs • Clock Rates to 1 GHz – 250-ps Output Transition Times – 0.12 ps Typical Intrinsic Phase Jitter – Less than 630 ps Propagation Delay Times • 2.5-V or 3.3-V Supply Operation • 2-mm x 2-mm Small-Outline No-Lead Package APPLICATIONS • PECL-to-LVDS Translation • Clock Signal Amplification DESCRIPTION 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 the Q output from 300 mV to 860 mV either by leaving it open (NC), grounded, or tied to VCC. (When left open, the Q output defaults to 575 mV.) The Q on the SN65LVx19 defaults to 575 mV as well. Both devices provide a voltage reference (VBB) of typically 1.35 V below VCC for use in receiving single-ended PECL input signals. When not used, VBB should be unconnected or open. All devices are characterized for operation from –40°C to 85°C.
