AZP92 PECL/ECL ÷1, ÷2 Clock Generation Chip with Selectable Enable www.azmicrotek.com FEATURES DESCRIPTION • 3.0V to 5.5V Operation • Selectable Divide Ratio • Selectable Enable Polarity and Threshold (CMOS or PECL) • High Bandwidth o 1.5+ GHz (÷1) o 3.0+ GHz (÷2) • -145 dBc/Hz (÷1) Typical Noise Floor • -151 dBc/Hz (÷2) Typical Noise Floor The AZP92 is a ÷1 or ÷2 clock generation part specifically designed to accommodate Colpitts or Pierce based oscillators. Features are incorporated to reduce board components. A voltage reference and input biasing allows for easy oscillator interface. The AZP92 provides a ÷ 2 mode of operation for more frequency options and is selectable with a single connection. A selectable enable is also provided which doubles as a reset when the AZP92 is in ÷2 mode. With a single connection, the enable can be selected to operate as active high or active low.

AZP92 PECL/ECL ÷1, ÷2 Clock Generation Chip with Selectable Enable ENGINEERING NOTES The AZP92 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 AZP92 functions as a standard receiver. If DIV-SEL is connected to VEE, it functions as a ÷2 divider. A selectable enable is provided which also functions as a reset when the ÷2 mode is selected. 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 resistor. Leaving EN-SEL open or connecting it to VEE will select 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 pull-down resistor is selected which disables the outputs whenever EN is left open. Connecting the EN-SEL to VEE with a 20kΩ resistor will select 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). This default logic condition can be overridden by connecting the EN to VCC with an external resistor of ≤20kΩ. Refer to the enable truth table on the next page for detailed operation. The AZP92 provides a VBB with an 1880Ω internal bias resistor from D to VBB. 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.
