3 Description

Texas Instruments' Bulk-Acoustic Wave (BAW) is a

micro-resonator technology that enables integration of

high-precision BAW resonator directly into packages

with ultra-low jitter clock circuitry. BAW is fully

designed and manufactured at TI factories like other

silicon-based fabrication processes.

The LMK6x device is an ultra-low jitter, fixed-

frequency oscillator which incorporates the BAW

as the resonator source. The device is factory-

programmed per specific operation mode, including

frequency, voltage, output type, and function pin. With

a high-performance fractional frequency divider, the

LMK6x is capable of producing any frequency within

the specified range providing a single device family for

all frequency needs.

The high-performance clocking, mechanical stability,

flexibility, and small package options for this device

are designed for reference and core clocks in high-

speed SERDES used in telecommunications, data

and enterprise network, and industrial applications.
