NB7N017MMN

Clock Generators, PLLs, Frequency Synthesizers Overview

The NB7N017MMN is a high-speed 8-bit dual modulus programmable divider/prescaler manufactured by onsemi using SiGe technology. It features CML outputs capable of switching at input frequencies exceeding 3.5 GHz, with internal 50-ohm source termination resistors to VCC generating a 400 mV output amplitude. The device includes differential CLK, CE, and SEL inputs that accept RSECL, ECL, LVDS, LVCMOS, LVTTL, and CML signals. It operates within a positive supply range of 3.0 V to 3.465 V (VEE = 0 V) or a negative supply range of -3.0 V to -3.465 V (VCC = 0 V). The component is housed in a QFN-52 package.

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the specific ordering suffix for the required packaging configuration. The MN suffix indicates a QFN-52 tray package containing 260 units. Confirm RoHS compliance status if lead-free specifications are mandatory for the assembly process. Ensure the procurement channel provides valid traceability documentation for this discontinued component series.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this component when an input frequency greater than 3.5 GHz is required alongside dual-modulus programmability. Verify compatibility with the system's power supply architecture, as it supports both positive and negative CML configurations. Ensure the PCB layout accommodates the QFN-52 exposed pad thermal requirements and maintains impedance matching for the differential CML inputs and outputs.

Clock Generators, PLLs, Frequency Synthesizers Part Context

The NB7N017MMN belongs to the NB7N017M family of prescalers from onsemi. It is specifically designated with the MN suffix, which corresponds to the QFN-52 package format.
