The 5036 series are 2.5V operation, differential LV-PECL output oscillator ICs. They support 50MHz to 400MHz 3rd overtone oscillation and 50MHz to 600MHz fundamental oscillation. The devices are fabricated using a proprietary BiCMOS process, enabling a high-frequency oscillator circuit and differential LV-PECL output buffer to be incorporated on a single chip. The 5036 series can be used to construct high-frequency LV-PECL output oscillators.
