TDA6650ATT Datasheet, PDF (23/54 Pages) NXP Semiconductors – 5 V mixer/oscillator and low noise PLL synthesizer for hybrid terrestrial tuner (digital and analog)

NXP Semiconductors
TDA6650ATT; TDA6651ATT
5 V mixer/oscillator and low noise PLL synthesizer
Table 20. Characteristics …continued
V_CCA = V_CCD = 5 V; T_amb = 25 °C; values are given for an asymmetrical IF output loaded with a 75 Ω load or with a
symmetrical IF output loaded with 1.25 kΩ; positive currents are entering the IC and negative currents are going out of the IC;
the performances of the circuits are measured in the measurement circuits Figure 27 and 28 for digital application or in the
measurement circuits Figure 29 and 30 for hybrid application; unless otherwise specified.
