The Texas Instruments CDC3RL02BYFPR is a dual-channel clock fan-out buffer designed for applications requiring minimal additive phase noise and robust fan-out capabilities. This device buffers a single clock source, such as a temperature-compensated crystal oscillator (TCXO), to multiple peripherals.
Key electrical specifications include a core supply voltage of 1.8V and an output supply voltage of 1.8V. It supports both sine and square wave inputs and provides square wave outputs. The buffer offers a typical additive RMS jitter of 370 fs and a typical output skew of 500 ps. The operating temperature range is -40°C to 85°C.
Designed for portable end-equipment, the CDC3RL02BYFPR features an integrated Low-Drop-Out (LDO) voltage regulator that accepts input voltages from 2.3V to 5.5V and outputs a regulated 1.8V at 50mA, which can be used to power peripheral devices like a TCXO. The adaptive clock output buffers minimize EMI emissions and maintain signal integrity.
The component is housed in an ultra-small 8-bump YFP (DSBGA) package, measuring 1.8 mm², with a 0.4mm pitch. It also comes in a WCSP package (0.8mm x 1.6mm). The mounting type is surface mount.
