5 VECL Voltage Controlled Oscillator Amplifier MC100EL1648 Description The MC100EL1648 is a voltage controlled oscillator amplifier that requires an external parallel tank circuit consisting of the inductor (L) www.onsemi.com and capacitor (C). A varactor diode may be incorporated into the tank circuit to provide a voltage variable input for the oscillator (VCO). 8 This device may also be used in many other applications requiring 8 1 a fixed frequency clock. 1 The MC100EL1648 is ideal in applications requiring a local SOIC8 NB TSSOP8 oscillator, systems that include electronic test equipment, and digital D SUFFIX DT SUFFIX highspeed telecommunications. CASE 75107 CASE 948R02 The MC100EL1648 is based on the VCO circuit topology of the MC1648. The MC100EL1648 uses advanced bipolar process MARKING DIAGRAMS* technology which results in a design which can operate at an extended frequency range. The ECL output circuitry of the MC100EL1648 is not a traditional 8 8 open emitter output structure and instead has an onchip termination K1648 1648 emitter resistor, R , with a nominal value of 510 . This facilitates ALYW E ALYW direct accoupling of the output signal into a transmission line. 1 1 Because of this output configuration, an external pulldown resistor is not required to provide the output with a dc current path. This output is SOIC8 NB TSSOP8 intended to drive one ECL load (3.0 pF). If the user needs to fanout the signal, an ECL buffer such as the EL16 (EL11, EL14) type Line A = Assembly Location Receiver/Driver should be used.
