GC1012A General Description
Fabricated in high speed CMOS technology, the GC1012A chip is an all digital tuner which can downconvert and band limit signals from wide band digitized sources. At full rate operation (80 MHz input rate), the input bandwidth can be up to 40 MHz wide. Any signal within the input bandwidth can be down-converted to zero frequency, low pass filtered, and output at a reduced sample rate. The chipÕs output can be formatted as either a complex data stream, or as a real data stream. The complex samples are output at rates equal to FO=FCK/D, where FO is the output rate, D is 1, 2, 4, 8, 16, 32 or 64 and FCK is the input sample (clock) rate. The real output rates are FO=2FCK /D for D equal to 2, 4, 8, 16, 32, or 64.
The signal is low pass filtered to remove out of band energy before the sample rate is decreased. The filterÕs out of band rejection is over 75 dB and its passband ripple is less than 0.2 dB peak to peak. The passband of the output filter covers 80% of the output bandwidth.
The 28 bit accumulator in the chipÕs digital oscillator circuit provides a tuning accuracy equal to the input clock rate divided by 228. The tuning resolution at a clock rate of 50 MHz is less than 0.2 Hz giving a tuning accuracy of +/- 0.1 Hz. The phase noise in the oscillator is low enough to provide a spur free dynamic range of over 75 dB.
The chipÕs output circuit allows the user to select a real or complex data output format, to select spectral inversion, or to offset the output spectrum by half of the output sample rate. The outputÕs signal gain can be adjusted in 0.03 dB steps. The word size of the output samples are either 10, 12, 14, or 16 bits.
On chip diagnostic circuits are provided to simplify system debug and maintenance.
The chip receives configuration and control information over a microprocessor compatible bus consisting of an 8 bit data I/O port, a 4 bit address port, a read/write bit, and a control select strobe.
I and Q output registers can be read from the control port to allow an external processor to monitor or process the chipÕs output samples. These registers are valuable for monitoring the chipÕs output power in order to set and adjust gain levels.
