MXL241SF Datasheet | MAXLINEAR

Description The Mx L241SF is a single-chip integrated tuner and demodulator receiver IC targeting all global digital cable standards (ITU-T J.83 Annex A [DVB-C], Annex B [US Cable] and Annex C). The Mx L241SF can also receive and demodulate OOB FDC signals without FEC processing. The interface plies with the open cable - cable card interface specification (OC-SP-CCIF2.0). The Mx L241SF is pliant to all SCTE40 requirements and all SCTE55-1 requirements in OOB mode. Broadband input filter, channel filter, automatic gain control, LO generation, PLL and demodulation functions are integrated on the chip, simplifying board-level design and faster design cycle. High integration along with a small device footprint enables a very pact design, reduced bill-of-materials cost, and low power consumption. In J.83 mode, The Mx L241SF takes an RF input signal from 44 to 1002MHz and outputs MPEG transport. In OOB mode, the Mx L241SF takes an RF of 70 to 130MHz and converts it to CRX and DRX. All functions are controlled by I2C interface. The IC can operate with a single 3.3V supply or with both 3.3V and 1.8V supplies for lower power consumption. The Mx L241SF is available in a 6 x 6 mm2 40-pin QFN package.
