DESCRIPTION

· The FT9-TFC is a highly integrated time and frequency synchronizing module that receives a 1PPS reference input and generates a 1PPS output and up to two single-ended clock outputs phase-locked and aligned to the rising edge of the 1PPS output pulse. It integrates low phase noise frequency clock translation and supports multiple filter bandwidth options from <1mHz to 0.1 Hz.

FEATURES

· Phase locks to one incoming 1PPS reference input.
· Generates two single-ended low jitter clock outputs derived from an external VCXO.
· Precision phase alignment of frequency outputs to 1PPS phase-locked output.
· Pre-configured APLL and default NPLL settings for three master clock types.
· Flexible status indicators for Lock and LOS/Holdover conditions.
· Flexible external 10MHz MCLK/Holdover options.
· Internal VCXO supports up to 160 MHz clock output frequency range.
· Programmable output dividers from VCXO frequency.
· Automatic compensation of external CC correctable OCXO module.
· Programmable NPLL bandwidth settings for 1PPS disciplining.
· I2C Interface for system communication and programming.
· 3.3VDC supply voltage.
· -40°C to 105°C operating temperature range.
· 9.2x9.2mm 16pin QFN surface mount package.
