NB3V8312CMNG

Clock Buffers, Drivers Overview

The NB3V8312CMNG is a high-performance, low-skew LVCMOS fanout buffer manufactured by onsemi. It distributes one single-ended LVCMOS or LVTTL clock input to twelve LVCMOS outputs with a maximum operating frequency of 250 MHz. The device features synchronous clock enable and output enable controls, allowing outputs to be tri-stated or held low. It supports dual supply configurations where the core voltage (VDD) can be 3.3 V, 2.5 V, or 1.8 V, while the output supply (VDDO) operates at the same or lower voltage, provided VDD ≥ VDDO. This architecture enables lower power consumption and output-level compatibility. The component is housed in a 32-pin QFN package.

• Test and measurement equipment

Clock Buffers, Drivers Procurement Notes

Verify the specific ordering suffix to confirm the package type and shipping quantity. The CMNG suffix indicates a QFN32 package supplied in tubes. Ensure that the required lead time and packaging specifications align with production schedules. Confirm compliance with RoHS directives and check for any recent product change notices that may affect availability or specifications before finalizing procurement orders.

Clock Buffers, Drivers Selection Notes

Select this component when a single clock source must drive multiple loads with minimal skew. The dual-supply capability allows optimization of power dissipation by lowering the output voltage relative to the core. Ensure the input signal meets the specified LVCMOS or LVTTL amplitude requirements. Verify that the thermal resistance characteristics of the QFN32 package are adequate for the intended ambient temperature and airflow conditions.

Clock Buffers, Drivers Part Context

This part belongs to the NB3V8312C family of ultra-low jitter fanout buffers. The family includes variants with different packages, such as the LQFP-32 option. These devices are designed for high-speed digital systems requiring precise clock distribution. The NB3V8312C series addresses the need for low phase noise and controlled propagation delay in complex electronic architectures.

Clock Buffers, Drivers Replacement Considerations

Direct substitutes within the same family include the NB3V8312CFAG and NB3V8312CFAR2G, which utilize the LQFP-32 package instead of the QFN32 form factor. When replacing, ensure the pinout compatibility between the QFN and LQFP packages is managed through PCB design adjustments if necessary.
