SL1935D

SL1935 Single Chip Synthesized Zero IF Tuner April 2004 Features Single chip synthesised tuner solution for quadrature down conversion, L-band to Zero IF. DVB compliant, operating dynamic range -70 to -20dBm. Compatible with DSS and DVB variable symbol rate applications. Selectable baseband path, programmable through I2C bus. Excellent quadrature balance up to 30MHz baseband Excellent immunity to spurious second harmonic (RF and LO) mixing effects. Low oscillator phase noise and reradiation. High output referred linearity for low distortion and multi channel application. Integral fast mode compliant I2C bus controlled PLL frequency synthesiser, designed for high comparison frequencies and low phase noise performance. Buffered crystal output for clocking QPSK demodulator. ESD protection (Normal ESD handling procedures should be observed). Ordering Information SL1935D/KG/NP1P (Tubes) 36 pin SSOP SL1935D/KG/NP1Q (Tape and Reel) 36 pin SSOP Description The SL1935 is a complete single chip I2C bus controlled Zero IF tuner and operates from 950 to 2150MHz. It includes an on-board low phase noise PLL frequency synthesiser and low noise LNA/AGC. The SL1935 is intended primarily for application in digital satellite Network Interface Modules and performs the complete tuner function. The device contains all elements necessary, with the exception of local oscillator tuning network and crystal reference, to produce a high performance I(n-phase) & Q(uadrature) downcon...
