TCXO Clock Buffers

The TCXO (SL188xx) family is a high performance 3-output LVCMOS TCXO clock buffer with low additive phase noise and low power dissipation. Each output clock can be controlled independently by separate output enable pins. The SL188xx clock buffers can be used in baseband mobile RF applications including WLAN, Bluetooth, and DVB-H as an input clock reference. The device operates from single power supply from 1.70 V to 3.65 V and supports operating temperature from -40 °C to 85 °C.
