Description
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 multi-mode 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 operational temperature is
鈥?0擄C to +85擄C.
