Welcome Here  Shenzhen Mingjiada Electronics Co., Ltd.

Product Overview:

The LE9541DUQCT Ringing SLIC device is a single channel device equivalent to channel 1 of the LE9540. It offers the same 6x6 40-pin QFN package as the ELE9540 for "dual" single channel or dual channel PCB designs. LE9551 also corresponds to a channel of LE9540. It offers small 4x5 28 pin QFN and is optimized for single channel applications. These devices provide battery feed and supervise voice loops found in short-loop cable applications. These devices are optimized to interface with Broadcom BCM338x or bcm339x family SoCs. Operation control and status reporting communicate via a serial interface with reset. These devices support broadband applications and GR909 testing.
