3 Description

Texas Instruments' Bulk-Acoustic Wave (BAW) is

a micro-resonator technology that enables the

integration of high-precision and ultra-low jitter clocks

directly into packages that contain other circuits. BAW

is fully designed and manufactured at TI factories like

other silicon-based fabrication processes.

The LMK6x device is a low jitter, fixed-frequency

oscillator which incorporates the BAW as the

resonator source. 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

device is factory-programmed per specific operation

mode, including frequency, voltage, output type, and

function pin. Contact a TI representative for additional

frequencies or other options.

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.
