Product Summary
The BCM3405KQTEG is a highly integrated silicon tuner. The BCM3405KQTEG containing an LNA and the RF AGC, is the companion part to it. This two-chip solution supports both 64-QAM and 256-QAM digital cable modem applications. The device is specifically designed to work with Broadcom’s industry-leading BCM3345, BCM3360, BCM3348, and BCM3250 single-chip cable modems, and form an attractive alternative to traditional can tuners in any cable modem design. The BCM3405KQTEG supports an IF output frequency range of 36 MHz through 44 MHz and specifically supports the 36.125 MHz and 43.75 MHz center frequencies for the PAL and NTSC standards. The applications of the BCM3405KQTEG include Cable modems, Cable set-top boxes.
