N/A

The AZ100LVEL16VR is a specialized oscillator gain stage with high gain output buffer including an enable.

The QHG/Q¯ HG outputs have a voltage gain several times greater than the Q/Q¯ outputs.

The AZ100LVEL16VR provides a selectable enable that allows continuous oscillator operation. See truth table

below for enable function. If Enable pull-up is desired in the CMOS mode, an external ≤20kΩ resistor connecting

EN to VCC will override the on-chip pull-down resistor. The AZ100LVEL16VR also provides a VBB and 470Ω

internal bias resistors from D to VBB and D¯ to VBB. The VBB pin can support 1.5mA sink/source current. Bypassing

VBB to ground with a 0.01 µF capacitor is recommended.

Outputs Q/Q¯ each have a selectable on-chip pull-down current source. See truth table below for current source

functions. External resistors may also be used to increase pull-down current to a maximum total of 25mA.

Outputs QHG/Q¯ HG each have 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 /Q¯ HG operate as standard PECL/ECL. When VEEP is

connected to VEE , the current sources are activated. The QHG /Q¯ HG pull-down current can be decreased, by using a

resistor to connect from VEEP to VEE.

NOTE: Specifications in the ECL/PECL tables are valid when thermal equilibrium is established.
