DESCRIPTION
The AZ10/100EL16VO is an oscillator gain stage with a high gain output buffer including an enable. The
Q
HG
/Q
HG
outputs have a voltage gain several times greater than the Q/Q outputs. An enable input (ˉˉ) allows
continuous oscillator operation. When ˉˉ is LOW or floating (NC), input data is passed to both sets of outputs.
When ˉˉ is HIGH, the Q
HG
/Q
HG
outputs will be forced LOW/HIGH respectively, while input data will continue to
be passed to the Q/Q outputs. The ˉˉ input can be driven with an ECL/PECL signal or a CMOS logic signal.
The input impedance of the D/D inputs remain constant for all operating modes since forcing the outputs via the
ˉˉ pin does not power-down the chip but only disables the high gain Q
HG
/Q
HG
outputs.
Input protection diodes are included on the D/D inputs for enhanced ESD protection.
The EL16VO also provides a V
BB
output that supports 1.5mA sink/source current. When used, the V
BB
pin
should be bypassed to ground or V
CC
via a 0.01
μ
F capacitor.
Any used output must have an external pull down resistor. For 3.3V operation, an 180
resistor to V
EE
is
recommended if an AC coupled load is present. At 5.0V, a 330
resistor is recommended for the AC load case.
Alternately, a 50
load terminated to V
CC
– 2V or the Thevenin equivalent may be driven directly. Unused outputs
may be left floating (NC).
NOTE: Specifications in ECL/PECL tables are valid when thermal equilibrium is established.
