DESCRIPTION
µPB1505GR is a silicon prescaler IC operating up to 3.0 GHz and divided by 256, 128, 64. Due to 3.0 GHz operation and high division, this IC can contribute to produce BS/CS tuners with kit-use of 17K series DTS controller or standard CMOS PLL IC. The package is 8 pin plastic SOP suitable for surface mounting.
This IC is manufactured using NEC’s 20 GHz fTNESATIIIsilicon bipolar process. This process uses silicon nitride passivation film and gold electrodes. These materials can protect the chips from external pollution and prevent corrosion/migration. Thus, this IC has with excellent performance, uniformity and reliability.
