DVB-S2/S/T2/T/C Combo Demodulator IP

Description and Features

The is a single-chip DVB-T, T2, C, S and S2 demodulator IP core extratced from production chip and silicon proven IP core. Its Operation is exclusive in that only one signal (standard) can be processed at any time. The DVB-T2 demodulator features microcontroller assisted operation enabling the fast tracking and response times demanded by the T2 standard. For the T, C, S and S2 standards, where the demands for immediate response are much lower, classical software control from the host processor has been implemented. Even though the silicon implementation is highly optimized, allowing each standard to share common hardware blocks, effort has been made to maintain a common look and feel with the established product line. Optimization of the T2 microcode requires additional compilers which are, for the moment, supported exclusively by T2M. The DVB T, T2 and C demodulators share a common input which may be operated in ZIF mode or in IF mode. Silicon as well as traditional CAN tuners are supported through a flexible IF/baseband interface with IF/BB AGC and I2C control. A separate input is implemented for the DVB-S and S2 demodulators.This is single-channel tuner range is fully supported. Furthermore, the flexible ZIF IQ inputs, RF AGC and I2C allow the use of third-party tuner solutions when required.
