640455-9 Datasheet
640455-9 Price The pPB1506GV and uPB1507GV are 3.0 GHz input, high division silicon prescaler ICs for analog DBS tuner applications. These ICs divide-by-256, 128 and 64 contribute to produce analog DBS tuners with kit-use of 17 K series DTS controller or standard CMOS PLL synthesizer IC. The pPB1506GV/,uPB1507GV are shrink package versions of the ,uPB586G/588G or ,uPB1505GR so that these smaller packages contribute to reduce the mounting space replacing from conventional ICs. The ,uPB1506GV and ,uPB1507GV are manufactured using NEC's high fT NESATTMIV silicon bipolar process. This process uses silicon nitride passivation film and gold electrodes. These materials can protect chip surface from external pollution and prevent corrosion/migration. Thus, these ICs have excellent performance, uniformity and reliability. 640455-9 on stock
The CNA (cable-not-active) terminal provides a high when there are no twisted-pair cable ports receiving incoming bias (i.e., they are either disconnected or suspended), and can be used along with LPS to determine when to power-down the PD11394P23. The CNA output is not debounced. When the PD terminal is asserted high, the CNA detection circuitry is enabled (regardless of the previous state of the ports) and a pull-down is activated on the RESET terminal so as to force a reset of the PD11394P23 internal logic. |
