NB3H5150MNTXG

The NB3H5150MNTXG from ON Semiconductor is a high-performance, low-noise multi-rate clock generator. It utilizes a single PLL to synthesize up to four distinct frequencies from a 25 MHz input reference. The input can accept various signal types including crystal, LVCMOS/LVTTL, LVPECL, HCSL, or LVDS.

This device offers flexible output configurations, with three banks supporting selectable frequencies from 25 MHz to 156.25 MHz, and a fourth bank capable of generating integer and FRAC-N frequencies up to 161.1328 MHz. Each output block can be configured as two single-ended LVCMOS outputs or one differential LVPECL pair. The output voltage supplies are independently powered, supporting 1.8 V, 2.5 V, or 3.3 V for LVCMOS and 2.5 V/3.3 V for LVPECL.

Designed for applications in telecom, networking, and Ethernet, the NB3H5150MNTXG operates over an ambient temperature range of -40°C to +85°C. It features an I2C and SMBus compatible serial interface for programming various functions, including frequencies and output levels. The device is housed in a 32-pin QFN package (5x5 mm).

Key electrical characteristics include ultra-low phase jitter performance, with less than 0.3 ps RMS for integer-N outputs and 1 ps RMS for FRAC-N outputs. Output rise and fall times are rated at 300 ps for LVPECL and 1000 ps for LVCMOS. The device supports flexible input/core and output power supply combinations.
