General Description

The XM-A7F4-0609D is an Integer-N / Fractional-N PLL Frequency Synthesizer with integrated VCO featuring IDT’s 8V97053L (GSM1800 Grade) provided as a drop-in on an 0609 format.  The drop-in is a complete circuit with configurable loop amplifier.  A compatible Bias/Control board provides for easy prototype control using our X-MWcontroller.

The XM-A7F4-0609D PLL block is designed to integrate with other X-MWblocks.   Use a compatible Quartz based OCXO reference (like the XM-A2L3-0809D) to drive the PLL to improve the close-in phase noise and stability.

The XM-A7F4-0609D can also be purchased in a connectorized Housing XM-A7F4-0609C and can easily be integrated with other X-MWblock drop-ins to build IMAs in standard X-MWblock Housings or Custom Housings.
