N343532LQF7N Datasheet Low frequency noise becomes a great concern in DCR [14], as significant gain is allocated to baseband stages after the mixer. Weak baseband signal levels of a few millivolts are still very vulnerable to noise. This requires stronger RF stage gain to alleviate the poor noise figure of baseband blocks, but of course this must be traded against the linearity problems, just described, that accompany higher RF gain.

N343532LQF7N on stock 1. Pad Locations 2T and 6T are true no-connects. However, they are defined as SA address inputs in x18 LW SRAMs. 2. Pad Location 6U must be left unconnected. It is used by Sony for internal test purposes. 3. Pad Location 3R is defined as an Ml mode pin in LW SRAMs. However, it must be tied "high" in this device. 4. Pad Location SR is defined as an M2 mode pin in this device. It must be tied "high" or "low". When M2 is tied "high", this device functions as a conventional 16Mb R-L SRAM. When M2 is tied "low", this device functions as an Error-Correcting 8Mb R-L SRAM. 5. Pad Location 2B is defined as an SA address input in 16Mb LW SRAMs. However, it functions as a conventional SA address input in this device only when M2 is tied "high". It is ignored in this device when M2 is tied "low". 6. Pad Location 4F is defined as a G output enable input in LW SRAMs. However, it must be tied "low" in this device. Amplifier-sequenced receiver operation has several interesting char- acteristics that can be exploited in system design. The RF amplifiers in an amplifier-sequenced receiver can be turned on and off almost instantly, allowing for very quick power-down (sleep) and wake-up times. Also, both RF amplifiers can be off between ON sequences to trade-off receiver noise figure for lower average current consump- tion. The effect on noise figure can be modeled as if RFAl is on continuously, with an attenuator placed in front of it with a loss equivalent t0 1 0'I0910(RFAl duty factor), where the duty factor is the average amount of time RFAl is ON (up t0 50%). Since an amplifier-sequenced receiver is inherently a sampling receiver, the overall cycle time between the start of one RFAl ON sequence and |
