MxL692数据手册RF/IF射频/中频RFID的射频接收器规格书PDF

描述 Description

The MxL692 is a single-chip, integrated tuner and demodulator receiver that targets digital TV, single/multi-channel STB, USB/WiFi adapter, and WiFi/wired/RF Smart antenna system applications for the ATSC standard and cable applications for the global digital cable standards ITU-T J.83 Annexes (A, B, and C).

The MxL692 takes an RF input signal from 44 MHz to 1006 MHz, and outputs an MPEG TS in serial or parallel format. With its high-level of integration, the chip integrates

the following to simplify the board-level design:

• Broadband input filter

• Channel filter

• AGC

• LO

• PLL

• Demodulators

The device comes in a small 5 x 5 mm QFN package, enabling a very compact design, reduced BOM cost, and lower power consumption.

The MxL692 is controlled through an I2C interface. The IC supports either single supply operation using 3.3V, or dual supply operation using 3.3V and 1.8V.
