STCD1020, STCD1030, STCD1040

Multi-channel clock distribution circuit

Features

■ 2, 3 or 4 outputs buffered clock distribution

■ Single-ended sine wave or square wave clock

input and output

■ Individual clock enable for each output

■ Lower fan-out on clock source

TDFN (8, 10 or 12 lead)

■ No AC coupling capacitor needed at the input

■ Ultra-low phase noise and standby current

Description

(a)

■ 2.5 V to 3.6 V supply voltage

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.

■ 10 pF typical load driving capability

■ Available in TDFN packages

– STCD1020 - 8-lead (2 mm x 2 mm)

– STCD1030 - 10-lead (2 mm x 2.5 mm)

– STCD1040 - 12-lead (2 mm x 3 mm)

■ Operational temperature : –40°C to 85°C

Applications

■ Multi-mode RF clock reference

■ Baseband peripheral devices clock reference

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

–40°C to +85°C.
