Description
STCD1020, STCD1030, STCD1040
The STCD1020, STCD1030 and STCD1040 are 2, 3 or 4 outputs unity gain clock
distribution circuits, which are used to provide a common frequency clock to multimode
mobile RF applications. It can also be used for those baseband peripheral applications in a
mobile phone such as WLAN, Bluetooth, GPS and DVB-H as a clock reference. The
STCD1020, STCD1030 and STCD1040 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 if the connected device does not need the clock. The
STCD1020, STCD1030 and STCD1040 accept commonly used mobile master clock
frequencies ranging from 10 MHz to 52 MHz.
The STCD1020, STCD1030 and STCD1040 are available in 2 mm x 2 mm 8-lead, 2 mm x
2.5 mm 10-lead and 2 mm x 3 mm 12-lead TDFN packages and can be operated with a
single 2.8 V (or 1.8 V) supply. The operating temperature is –40 °C to +85 °C.
