The MC100EL1648 is a low power voltage controlled oscillator that can be used in many applications requiring a fixed frequency clock. It is based on the VCO circuit topology of the MC1648 and is realized using Motorola's MOSAIC III advanced bipolar process technology, allowing it to operate at a higher frequency while consuming less current compared to the MC1648. The MC100EL1648 features ECL output circuitry with an on-chip termination resistor, enabling direct AC-coupling of the output signal into a transmission line.
The Motorola MC100EL1648 is a low-power voltage-controlled oscillator (VCO) designed for applications requiring a local oscillator, such as electronic test equipment and digital high-speed telecommunications. It utilizes Motorola's MOSAIC III advanced bipolar process technology to operate at frequencies up to 1100 MHz while consuming only 20 mA of current at a 5.0 Vdc power supply.
