GC4116DK

This Designer's Kit is designed for use with the GC4116 quad transmit chip which contains four identical up-conversion channels. The up-convert channels accept real or complex signals, interpolate them by programmable amounts ranging from 32 to 5,792, and modulates them up to selected center frequencies. The modulated signals are then summed together and optionally summed with modulated signals from other GC4116 chips. Channels can be used in pairs to reduce the interpolation ratio down to 16 in order to process wider band input signals.

• GC4116 Diagnostic Configurations and Checksums (slwc005) - This download contains the diagnostic configurations used for built-in self test and initial diagnostics. It is highly recommended that these diagnostics are run as part of initial system debug.
• GC4116 Tap Filters (slwc004) - This download contains the GC4116 tap filter files.
• GC4116 BSDL Files for JTAG (slwc007) - This download contains the files that are required for JTAG boundary scan.
• GC4116 IBIS Board Simulation Zip File (slwc009) - This download is the IBIS board simulation file.
• GC4116 Configuration Files (slam014) - This download contains example register settings for common operating and test configurations. UMTS and IS95 (CDMA200-1X) configurations are included.
• GC4116 CDMA2000-1X Transmit Application Files (slwc031) - GC4116 configuration, coefficient and reference schematic files for using the GC4116 to transmit one to four CDMA2000-1X carriers. This configuration uses the built in resampler to phase equalize, and the internal channel filter to shape the carriers. Performance exceeds the IS95 and CDMA2000-1X specifications.
