PECL/LVDS Oscillator Gain Stage &  
Buffer with Selectable Enable  
FEATURES  
DESCRIPTION  
Minimizes External  
Components  
The AZV99 is a specialized oscillator gain stage with an LVDS output  
buffer including an enable. The selectable enable input allows continuous  
oscillator operation by only controlling the QHG /Q¯ HG outputs.  
Selectable Enable Polarity and  
Threshold (CMOS or PECL)  
3V to 5.5V Power Supply  
Similar Operation as  
AZ100LVEL16VT except  
with LVDS Outputs  
The AZV99 provides adjustable internal pull-down current sources for the  
Q/Q¯ outputs. Internal input biasing further reduces the number of needed  
external components

AZV99  
PECL/LVDS Oscillator Gain Stage &  
Buffer with Selectable Enable  
ENGINEERING NOTES  
FUNCTIONALITY MLP16 PACKAGE (AZV99L)  
The AZV99L provides a selectable enable (EN). Enable polarity and threshold can be selected to accommodate either  
CMOS/TTL or PECL input levels. If enable pull-up is desired in the CMOS/TTL mode, an external 20kresistor  
connecting EN to VCC will override the on-chip pull-down resistor.  
Outputs Q/Q¯ each have a selectable on-chip pull-down current source. External resistors may also be used to increase  
pull-down current to a maximum of 25mA (includes internal on-chip current source).  
The AZV99 also provides input biasing which is accomplished with a VBB and 470internal resistors from D to VBB and D¯ to  
VBB. The VBB pin supports 1.5mA sink/source current. VBB should be bypassed to ground with a 0.01µF capacitor.  
FUNCTIONALITY MLP8 PACKAGE (AZV99NB & AZV99ND)  
The AZV99NB and AZV99NB provide a PECL/ECL level enable input (¯E¯N¯). When the ¯E¯N¯ input is LOW, the Q¯ and  
QHG/Q¯HG outputs pass data from the inputs. When ¯E¯N¯ is HIGH, the Q¯ output continues to pass data while the QHG output  
is forced high and the Q¯HG output is forced low.  
Only the Q¯ output operates with a current source (4 mA) to VEE. This is accomplished by internal bonding of CS-SEL. An  
external resistor may also be used to increase pull-down current to a maximum of 25mA (includes 4mA on-chip current  
source).  
The AZV99NB and AZV99ND versions operate with a single ended data input (D). The D¯ input is internally bonded  
directly to the VBB pin bypassing the 470bias resistor.  
FUNCTIONALITY MLP8 PACKAGE (AZV99N) & MSOP8 PACKAGE (AZV99T)  
The AZV99N and AZV99T provide a CMOS/TTL level enable input (EN). When the EN input is HIGH, the Q¯ and  
QHG/Q¯HG outputs pass data from the inputs. When EN is LOW, the Q¯ output continues to pass data while the QHG output is  
forced high and the Q¯HG output is forced low.  
Only the Q¯ output operates with a current source (4 mA) to VEE. This is accomplished by internal bonding of CS-SEL. An  
external resistor may also be used to increase pull-down current to a maximum of 25mA (includes 4mA on-chip current  
source).  
The MSOP8 (T) and MLP8 (N) AZV99 operate with a single ended data input (D). The D¯ input is internally bonded  
directly to the VBB pin bypassing the 470bias resistor.
