Multichannel clock distribution circuit

The STCD22x0, STCD23x0 and STCD24x0 are 2, 3 or 4 output clock distribution circuits which accept external square wave or sine wave signals and output rail-to-rail (0 V to VTCXO) square wave signals. They are used to provide a common frequency clock to multimode mobile RF applications. They can also be used for those baseband peripheral applications in mobile phones such as WLAN, Bluetooth, GPS and DVB-H as the clock reference. The STCD22x0, STCD23x0 and STCD24x0 isolate each device driven by their clock outputs and minimize interference between the devices. Each of the clock buffers can be disabled to lower the power consumption whenever the connected device does not need the clock. The STCD22x0, STCD23x0 and STCD24x0 accept commonly used mobile master clock frequencies ranging from 10 MHz to 52 MHz.
