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 SN65LVx16) and fully differential inputs on the SN65LVx17.
The SN65LVx16 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 SN65LVx17 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.
