NOTES:
8. A = Production Tested, B = Based on Characterization, C = By Design.
9. Data is characterized by DC levels applied to MOD TXI and Q pins for 4 quadrants with LO output as reference or indirectly by the SSB
characteristics.
10. Power at the fundamental SSB frequency of two 6MHz, 90 degrees apart square waves applied at TXI and TXQ inputs. V
IH
= 3.0V,
V
IL
= 0.5V. LPF selected to 8.8MHz cutoff.
11. Cutoff frequencies are specified for both modulator and demodulator as the filter bank is shared and multiplexed for Transmit and Receive. Data
is characterized by observing the attenuation of the fundamental of a square wave digital input swept at each channel separately. The IF output
is down converted by an external wideband mixer with a coherent LO input for each of quadrature signals separately.
12. Typical ratio characterization with R
TUNE
set to 7.7MHz, LPF selected for 8.8MHz. TXI and TXQ Digital Inputs at two independent and aligned
11M chip/s, 2
