LMH2190 Quad Channel 27 MHz Clock Tree Driver with I²C Interface

Check for Samples: LMH2190

FEATURES

DESCRIPTION

The LMH2190 is a quad channel configurable clock

tree driver which supplies a digital system clock to

peripherals in mobile handsets or other applications.

It provides a solution to clocking issues such as

limited drive capability for fanout or longer traces,

protection of the master clock from varying loads and

frequency pulling effects, isolation buffering from

noisy modules, and crosstalk isolation. It has very low

phase noise which enables it to drive sensitive

modules such as Wireless LAN and Bluetooth.

•

1 Input Clock, 4 Output Clocks

Supports both Square or Sine Wave Input

1.8V Square Wave Clock Outputs

Skewed Clock Outputs

Independent Clock Request

High Isolation of Supply Noise to Clock Input

High Output to Output Isolation

Output Drive up to 50 pF

The LMH2190 can be clocked up to 27 MHz, and has

an independent clock request pin for each clock

output which allows the peripheral to control the

clock. It features an integrated LDO which provides

an ultra low noise voltage supply with 10 mA external

load current which can be used to supply the TCXO

or other clock source.

The I²C serial interface can be used to override the

default configuration of the device to optimize the

LMH2190 for the application. Some of these

programmable features include setting the polarity of

both the clock and the clock request inputs. In

addition, the clock outputs have programmable output

drive current to optimize for the connected load. EMI

switching noise can be controlled by configuring

output drive and skew settings.

EMI Controlled Output Edges and EMI Filtering

Integrated 1.8V Low-Dropout Regulator

–

Low Output Noise Voltage

–

10 mA load Current

•

I²C Configurable up to 400 kHz (Fast Mode)

Ultra Low Standby Current

V_BATRange = 2.5V to 5.5V

APPLICATIONS

•

Mobile Handsets

PDAs

Portable Equipment

The LMH2190 quad clock distributor is offered in a

tiny 1.61mm x 1.61mm 16 bump DSBGA package. Its

small size and low supply current make it ideal for

portable applications.
