ON Semiconductor NB3RL02FCT2G

Description
The NB3RL02 is a lowskew, lowjitter 1:2 clock fanout buffer designed for portable endequipment, such as mobile phones. It features an integrated LDO and output control circuitry. The MCLK IN pin accepts a square or sine wave clock input, such as a temperaturecompensated crystal oscillator (TCXO). The two clock outputs are enabled by control inputs CLK_REQ1 and CLK_REQ2. The NB3RL02 has an integrated LowDropOut (LDO) voltage regulator that accepts input voltages from 2.3 V to 5.5 V and outputs 1.8 V at 50 mA. This 1.8 V supply is externally available to provide regulated power to peripheral devices, such as a TCXO. The adaptive clock output buffers offer controlled slewrate over a wide capacitive loading range, minimizing EMI emissions, maintaining signal integrity, and minimizing ringing caused by signal reflections on the clock distribution lines.
