DESCRIPTION The AZP94 is a specialized ÷1 or ÷2 clock generation part including an enable/reset function. The divide ratio is selected with the DIV-SEL pin/pad. When DIV-SEL is open (NC), the AZP94 functions as a standard receiver. If DIV-SEL is connected to VEE, it functions as a ÷2 divider. Enable (EN) functionality is selected with the EN-SEL pin/pad which has three valid states: open (NC), VEE, or connected to VEE via a 20kΩ ± 20% resistor. Leaving EN-SEL open or connecting it to VEE allows the EN pin/pad to function as an active high CMOS/TTL enable. When EN-SEL is open, an internal 75kΩ pull-up resistor is selected which enables the outputs whenever EN is left open. When EN-SEL is connected to VEE, an internal 75kΩ pulldown resistor is selected which disables the outputs whenever EN is left open. Connecting the EN-SEL to VEE with a 20kΩ resistor will allow the EN pin/pad to function as an active low PECL/ECL enable with an internal 75kΩ pull-down resistor. In this mode, outputs are enabled when EN is left open (NC). The default logic condition can be overridden by connecting the EN to VCC with an external resistor of ≤20kΩ. If the enable signal is CMOS (rail-to-rail) and the logic sense is active low (EN-SEL connected to VEE with a 20kΩ resistor), the EN pin/pad voltage swing must be reduced using two external resistors. Contact the factory for details. When the AZP94 is disabled, the Q and Q ¯ outputs are forced LOW and the input buffer is powered down to minimize feed through. This feature allows tristate compatible parallel output connections. Multiple AZP94 chip outputs can be wired together. Since both outputs are forced LOW in the disable mode, an enabled AZP94 can drive the output lines without interference from the unselected units. In addition, the AZP94 can be used in parallel connection with PECL/ECL parts whose outputs are high impedance when disabled. The EN pin/pad also functions as a reset when the ÷2 mode is selected. In the ÷2 mode, the counter resets when the outputs are disabled. 1630 S.

This feature allows AC coupling with minimal external components. The VBB pin supports 1.5mA sink/source current and should be bypassed to ground or VCC with a 0.01 μF capacitor. DIE (AZP94X) ¯ to BIAS. The AZP94X provides a VBB and a BIAS pad with 940Ω internal resistors from D to BIAS and D Connecting the BIAS pad to VBB allows D and D ¯ to be AC coupled with minimal external components. For single ended applications, D or D ¯ may be connected directly to VBB to form a single 1880Ω bias resistor. The VBB pin supports 1.5mA sink/source current. Whenever used, the VBB should be bypassed to ground or VCC with a 0.01 μF capacitor. TYPICAL TRISTATE COMPATIBLE OPERATION Tristate Compatible Operation The outputs of the AZP94 are emitter followers as shown in the left side of the drawing. When a part is disabled, both outputs are set in the LOW state. This allows a HIGH output from an enabled part to override a disabled output and pull the combined line HIGH as seen in the right hand side of the drawing. When the enabled part output is LOW, the combined line remains LOW. If all connected AZP94 parts are disabled, both output lines will be in the LOW state. NOTE: The specifications in the ECL/PECL tables are valid when thermal equilibrium has been established.
