AZ100LVEL16VR PECL/ECL Oscillator Gain Stage & Buffer with Selectable Enable www.azmicrotek.com FEATURES DESCRIPTION • Minimizes External Components • Selectable Enable Polarity and Threshold (CMOS or PECL) • High Bandwidth for ≥1GHz • Similar Operation as AZ100EL16VO • -147 dBc/Hz Typical Noise Floor The AZ100LVEL16VR is a specialized oscillator gain stage with a high gain output buffer including an enable function. The QHG/Q̄HG outputs have voltage gain several times greater than the Q/Q̄ outputs. It provides a selectable QHG/Q̄HG enable that allows continuous oscillator operation via the Q/Q̄ outputs. The AZ100LVEL16VR provides adjustable internal pull-down current sources for the Q/Q̄ outputs and optional 10mA current sources for the QHG/Q̄HG outputs. Internal input biasing further reduces the number of needed external components BLOCK DIAGRAM APPLICATIONS • Crystal or saw oscillators that require minimal external components.

AZ100LVEL16VR PECL/ECL Oscillator Gain Stage & Buffer with Selectable Enable ENGINEERING NOTES FUNCTIONALITY MLP 16 PACKAGE (AZ100LVEL16VRL) The AZ100LVEL16VR provides a selectable QHG/Q̄HG enable that allows continuous oscillator operation via the Q/Q̄ outputs. Table 3 shows the operating modes. Leaving EN-SEL open (NC) selects PECL/ECL operation for the EN pad/pin. In this mode the QHG/Q̄HG outputs are enabled when EN is left open (NC) or set to a PECL/ECL low. Connecting EN-SEL to VCC, VEE or VBB selects CMOS operation for the EN pad/pin. When EN-SEL is tied to VEE, the QHG/Q̄HG outputs are disabled when EN is left open (NC). When EN-SEL is tied to VCC or VBB, the QHG/Q̄HG outputs are enabled when EN is left open. This default logic condition can be overridden by a ≤ 20kΩ resistor connected to the opposite supply. The AZ100LVEL16VR also provides a VBB and 470Ω internal bias resistors from D to VBB and D̄ to VBB. The VBB pin supports 1.5mA sink/source current. VBB should be bypassed to ground or VCC with a 0.01 µF capacitor. Outputs Q/Q̄ each have a selectable on-chip pull-down current source. See Table 4 for the supported values. External resistors may also be used to increase pull-down current to a maximum total of 25mA for the Q/Q̄ outputs. Each of the QHG/Q̄HG outputs has an optional on-chip pull-down current source of 10mA. When pad/pin VEEP is left open (NC), the output current sources are disabled and the QHG /Q̄HG operate as standard PECL/ECL. When VEEP is connected to VEE, the current sources are activated. The QHG /Q̄HG pull-down current can be decreased by using a resistor between VEEP and VEE.

AZ100LVEL16VR PECL/ECL Oscillator Gain Stage & Buffer with Selectable Enable Figure 3 illustrates the timing sequences for the AZ100LVEL16VR in the MLP 16 package or as die. It is shown here with the enable operating in active Low mode with a PECL threshold. This mode is determined by leaving the EN-SEL open (NC). An active High enable with a CMOS/TTL threshold is also an option. D EN (PECL) Q Q QHG QHG Figure 3 - AZ100LVEL16VRL Timing Diagram FUNCTIONALITY MLP 8 PACKAGE (AZ100LVEL16VRNEG) A CMOS enable input (EN) allows continuous oscillator operation. When the EN input is HIGH or left open (NC), the Q̄ and QHG/Q̄HG outputs follow the data input. When EN is LOW, the QHG output is forced high and the Q̄HG output is forced low while Q̄ continues to follow the data input. The Q̄ output has an internal 4 mA current source to VEE, in most cases eliminating the need for an external pull-down resistor. The AZ100LVEL16VRNEG also provides biasing. Data input D is tied to the VBB pin through a 470Ω internal bias resistor while the inverting input D̄ is connected directly to VBB. The VBB pin supports 1.5mA sink/source current. VBB should be bypassed to ground with a 0.01 µF capacitor.
