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 highspeed

SERDES used in Telecommunications, Data

and Enterprise Network and Industrial applications.
