NB3RL02FCT2G

The NB3RL02FCT2G from On Semiconductor is a two-channel clock fanout buffer designed for low-skew and low-jitter applications. It is ideal for portable equipment such as mobile phones.

This buffer supports a master clock input and provides two clock outputs, controlled by CLK_REQ1 and CLK_REQ2 inputs. It operates with an input voltage range of 2.3 V to 5.5 V and can handle frequencies up to 80 MHz, with a typical operating frequency of 52 MHz. The device features adaptive clock output buffers that minimize EMI emissions and maintain signal integrity.

An integrated Low-Drop-Out (LDO) voltage regulator provides a regulated 1.8 V output, which can be used to power external clock sources like TCXOs. The NB3RL02FCT2G is offered in an ultra-small 8-ball Wafer-Level Chip Scale Package (WLCS) with a 0.4 mm pitch, optimized for very low standby current consumption.

Key electrical characteristics include low additive noise of -149 dBc/Hz at 10 kHz offset and output jitter of 0.37 ps (rms). It also meets stringent ESD performance requirements, exceeding JESD 22 standards for Human-Body Model, Machine Model, and Charged-Device Model.

The NB3RL02FCT2G is suitable for applications in cellular phones and Global Positioning Systems (GPS). It is mounted using a surface mount technique and operates within a temperature range of -40°C to 85°C.
