5 / 9 page Direct-Conversion Tuner IC for Digital DBS Applications _______________________________________________________________________________________ 5 Note 1: Minimum and maximum values are guaranteed by design and characterization over supply voltage. Note 2: With external 100 Ω termination resistor. Note 3: Driving differential load of 10k Ω || 15pF. Note 4: Two signals are applied to RFIN_ at fLO - 100MHz and fLO - 199MHz. VGC2 = 1V; VGC1 is set such that the baseband out- puts are at 590mVP-P. IM products are measured at baseband outputs but are referred to RF inputs. Note 5: Two signals are applied to RFIN_ at 1200MHz and 2150MHz. VGC2 = 1V, VGC1 is set such that the baseband outputs are at 590mVP-P. IM products are measured at baseband outputs but are referred to RF inputs. Note 6: PRFIN_ = -40dBm so that front end IM contributions are minimized. Note 7: Using L64733/L64734 demo board from LSI Logic. Note 8: Downconverted level, in dBc, of carrier present at fLO x 2, fLO = 1180MHz, fVCO = 590MHz, VFDOUB = 2.4V. Note 9: Downconverted level, in dBc, of carrier present at fO / 2, fLO = 2175MHz, fVCO = 1087.5MHz, VFDOUB = 2.4V. Note 10: Leakage is dominated by board parasitics. Note 11: VCPG1 = VCPG2 = VFDOUB = VINSEL = 0.5V, fFLCLK = 0.5MHz. Note 12: Measured at tuned frequency with PLL locked. All phase noise measurements assume tank components have a Q > 50. AC ELECTRICAL CHARACTERISTICS (continued) (VCC = 4.75V to 5.25V, VIOUT_ = VQOUT_ = 0.59VP-P, CIOUT_ = CQOUT_ = 10pF, fFLCLK = 2MHz, RIOUT_ = RQOUT_ = 10k Ω, VFDOUB = VINSEL = VCPG1 = VCPG2 = 2.4V, VPLLIN+ = VMOD+ = 1.3V, VPLLIN- = VMOD- = 1.1V, TA = +25°C. Typical values are at VCC = 5.0V and TA = +25°C, unless otherwise noted.)
