KEY FEATURES
Output rates up to 100 MSPS
Four identical up-convert channels
16 bit real or complex inputs
Four bit serial input ports, or memory mapped input
registers
Serial interface controller simplifies interfacing with
ASICs or DSP chips
Resampler circuit filters, pulse shapes and
resamples data to allow arbitrary input to output
sample rate conversion
Interpolation factors of
32 to 5,792 in each channel
16 to 32 by combining two channels
Independent frequency, phase and gain controls
User programmable 63 tap input filter
0.02 Hz tuning resolution
115 dB Spur Free Dynamic Range
90 dB or more image rejection
0.07 dB gain resolution
0.05 dB peak to peak passband ripple
The four channels are summed into a single output
signal
22 bit sum I/O path to merge outputs from multiple
GC4116 chips
8 to 22 bit 2’s complement or offset binary
output samples
Accepts QPSK or QAM symbol data directly,
performs transmit (pulse shape) filtering
Performs
pulse
shaping
equalization for IS95 and CDMA2000
Exceeds Damps, GSM, & IS95 requirements
Supports up to two 4 Mbaud channels.
Microprocessor interface for control
Built in diagnostics
Each GC4116 chip upconverts:
Four GSM, DAMPS, or 1X CDMA carriers, or
Two 3X CDMA2000 carriers, or
Two 3.84MB UMTS carriers
Power consumption at 70 MHz, 2.5 volts:
84 mW per DAMPS channel
107 mW per GSM channel
305mW per 3.84MB UMTS channel
Industrial temperature range (-40C to +85C)
