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, fixedfrequency

oscillator which incorporates the BAW

as the resonator source. The device is factoryprogrammed

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 highspeed

SERDES used in telecommunications, data

and enterprise network, and industrial applications.
