The C7 Advanced Frequency Controller
Radio Adventures Corp. is pleased to announce the availability of the C7 Advanced Frequency Controller chip. The Radio Adventures Corp. C7 is a high-performance, low-cost CMOS part developed for the amateur and commercial communications markets. Specifically, it has been designed to be the controller of a frequency locked loop, providing the frequency counter, correction pulses, control logic, two VFOs, and internal diagnostic software. The C7 also provides interfaces to a four-digit seven-segment LED display, serial memory, shaft encoder, key in, key out, receiver incremental tuning (RIT), and a 4 by 4 keypad. The C7’s high level of integration makes it simple to add a full suite of digital features to almost any equipment using a voltage controlled variable frequency oscillator.
The C7 covers the frequency range from DC to over 50 MHz with an update rate of 10 times per second. When used with an external EEPROM, the C7 offers 32 digital memories and a programmable display capable of accommodating almost any mixing scheme including inverse tuning, offsets, binary multipliers, and binary dividers. This allows the display to read correctly even when the measured frequency is different than the operating frequency. The C7 is useful in the construction of stable analog function generators, QRP rigs, home built radio equipment, and commercial radios. It can also be used as the core of a stand alone module providing a "digital home station", for up to sixteen different voltage tuned rigs. Unit price is $17.95 and is available immediately, board kits for evaluation or installation are also available. Please see our products page.
