DESCRIPTION
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 V
EE
, 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), V
EE
, or connected to V
EE
via a 20k
Ω
resistor. Leaving EN-SEL open or connecting it to V
EE
will select the EN pin/pad to function as an active
high CMOS/TTL enable. When EN-SEL is open, an internal 75k
Ω
pull-up resistor is selected which enables the
outputs whenever EN is left open. When EN-SEL is connected to V
EE
, an internal 75k
Ω
pull-down resistor is
selected which disables the outputs whenever EN is left open.
Connecting the EN-SEL to V
EE
with a 20k
Ω
resistor will select the EN pin/pad to function as an active low
PECL/ECL enable with an internal 75k
Ω
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 V
CC
with an external resistor of
≤
20k
Ω
. Refer to the enable truth table on the next page for detailed operation.
DIE (AZP92X)
The AZP92X provides a V
BB
and a BIAS pad with 940
Ω
internal resistors from D to BIAS and D to BIAS.
Connecting the BIAS pad to V
BB
allows D and D to be AC coupled with minimal external components. For single
ended applications, D or D may be connected directly to V
BB
to form a single 1880
Ω
bias resistor. The V
BB
pin
supports 1.5mA sink/source current. Whenever used, the V
BB
should be bypassed to ground or V
CC
with a 0.01
μ
F
capacitor.
MLP 8, 2x2 mm Package (AZP92NA)
The AZP92NA provides a V
BB
with an 1880
Ω
internal bias resistor from D to V
BB
. This feature allows AC
coupling with minimal external components. The V
BB
pin supports 1.5mA sink/source current and should be
bypassed to ground or V
CC
with a 0.01
μ
F capacitor.
NOTE: The specifications in the ECL/PECL tables are valid when thermal equilibrium has been established.
