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.

Figure 2 illustrates the timing sequences for the AZP92 in the ÷1 mode which is determined by leaving the DIV-SEL open
(NC). It also illustrates the enable in the active High mode being controlled by a CMOS signal. This mode is determined
by leaving the EN-SEL open (NC).
