-Samtec has many cable options which mate with the TFM series headers.
+Samtec has many cable options which mate with the TFM series headers. We have tested cables from the FHSC and SFSD series with the CM-PLL module.
 
+'''FHSC Series'''
+The [http://www.samtec.com/technical-specifications/Default.aspx?seriesMaster=fhsc FHSC series cable assemblies] use a flat ribbon of 50-ohm coaxial cables, with one cable per pin. The CM-PLL headers are compatible with either the end-launch or right-angle version of the FHSC cables. We recommend cables with right-angle connectors. The part number for this cable is '''FHSC-105-XX.XX-SBR-SBL-3''', where XX.XX is the cable length in decimal inches.
 
+'''SFSD Series'''
+The [http://www.samtec.com/technical-specifications/Default.aspx?seriesMaster=sfsd SFSD series cable assemblies] use discrete wires for each signal. These wires are not bound into a single cable, though this is easy to do yourself with tape or zip ties. The compatible part number is '''SFSD-05-28-F-XX.XX-DR-NUS'''
+
+The TFM headers on the CM-PLL are 0.50" pitch, 2x5 pin connectors. These are standard dimensions - there are likely additional cables from Samtec and other manufacturers which are compatible with the CM-PLL headers. If you opt for a different cable, ensure the cable maps signals as specified
