NB3RL02 Low Phase-Noise Two-Channel Clock Fanout Buffer The NB3RL02 is a low skew, low jitter 1:2 clock fan out buffer, ideal for use in portable end equipment, such as mobile phones.

With integrated LDO and output control circuitry.

The MCLK_IN pin has an AC coupling capacitor and will directly accept a square or sine wave clock input, such as a temperature compensated crystal oscillator (TCXO).

The minimum acceptable input amplitude of the sine wave is 300 mV peak <
