PECL/ECL Filter-Based Multiplier & Limiting Amp With Selectable Enable

The AZP81 is a specialized multiplier chip designed to be used with an external Filter It supplies three different gain paths. A low gain path is used with a Resonator usually a crystal (D/D to Q ). An intermediate gain path with fast output edges supplies a Filter (D/D to FLTRDR/FLTRDR ). A high gain limiting amp (AMPIN to QHG/Q HG) with a selectable enable provides industry standard 100k PECL/ECL outputs. When QHG/Q HG are disabled, the AZP81s Oscillator loop continues to operate. See truth table below for enable function. It also provides a VBB and 470 internal bias resistors from D/D to VBB and AMPIN to VBB. The VBB pin CAN support 1.5mA sink/source current. Bypassing VBB and D to ground with 0.01 to 0.1 F capacitors is recommended. Output Q has an on-chip 4mA pull-down current source while output FLTRDR has an on-chip 8mA pull-down current source. External resistors to VEE may also be used to increase pull-down current to a maximum of 25mA each. By Arizona Microtek, Inc.
