NBLVEP16VR 2.5V/3.3V/5V ECL Differential Receiver/Driver with Oscillator Gain Stage and Enabled High Gain Outputs
The NBLVEP16VR is an ECL/LVPECL oscillator gain stage with high−gain output buffers, selectable output enable and a feedback buffer. The NBLVEP16VR is a solution for crystal oscillators and SAW−based voltage−controlled oscillators. • Q and Q Outputs have Selectable 4 mA or 8 mA, Self Bias Current Sources • QHG and QHG have a Selectable 10 mA, Self Bias Current Sources • Synchronous Output Enable of the High−Gain Outputs with Selectable Disabled State • Selectable LVCMOS/LVTTL or LVPECL Level Input of the Output Enable Pin • Maximum Frequency > 2.5 GHz Typical • (LV)PECL Mode Operating Range: VCC = 2.375 V to 5.
