Video Timing Generator By Quotes None 400 MHz None  
The IP Core is a fully configurable video timing generator with the ability to support any video resolution up to 216  x 216 pixels in size. The module is compatible with a wide range of video DACs, CODECs and transceivers and provides a flexible solution for displaying digital or analogue video on an external TV, monitor or flat panel display.  The module is capable of clock speeds in excess of 400 MHz on some FPGA platforms, making it ideal for the latest generation HD and UHD video solutions. After resynchronizing the input pixels to the pixel-clock domain , the controller locks to the first frame (or field) of video. Once frame-lock is achieved, pixels are supplied on demand to the video timing control unit. This module generates the correct RGB video, sync and blanking information depending on the chosen timing parameters. Application Legacy (SD) and analogue video applications Digital TV and multimedia solutions HD, UHD and SUHD next generation digital video   Introduction
RF Power Amplifier Precorrection By Quotes None 150 MHz None  
The IP is a complete Digital Precorrection(Predistortion) system designed to compensate for the non-linear characteristic of a high-power RF Amplifier. The system is capable of adjusting both the gain and phase of a complex input signal.   This is achieved by means of a complex multiplication of the input with a complex polynomial function stored in the LT. The LT contains the inverse PA characteristic and is applied before the amplification stages (either at baseband or IF frequencies). By programming the LT with the inverse gain/phase PA  response,   the resultant PA response is linearized. After linearization, the output signal is much cleaner with reduced intermodulation distortion.  The system may be used in open-loop or closed-loop configuration. For open loop operation, the LUT coefficients are static and programmed during initial setup of the PA precorrection system. For   closed-loop operation, an external circuit may compare the baseband inputs and PA outputs and adjust the LUT coefficients dynamically in order to automate the linearization process. Application Precorrection of wide bandwidth signals such as UMTS, WCDMA and OFDM Power amplifier linearization for mobile Base-stations, Broadcasting etc. Precorrection of any type of digitally modulated signal where the signal envelope varies and therefore the instantaneous input power. Introduction
Periodic waveform generator By Quotes None 200 MHz None  
The IP Core is a high-precision Direct Digital Synthesizer 2 used for the generation of periodic waveforms. On each rising-edge of the sample clock, the phase in the phase accumulator is incremented by the value phase_inc.  This phase is quantized to 16-bits and passed as an address to a look-up table which converts the phase into a waveform. In addition to the quadrature outputs sin_out and cos_out, the IP also provides square wave and sawtooth outputs: squ_out and  saw_out.  All output values are 16-bit signed numbers.  Appliaction Digital up/down converters and mixers Versatile waveform generation Digital oscillators Digital modulation Introduction
Precision Tone Decoder By Quotes None 200 MHz None  
The IP is a precision tone decoder with the capacity to support either real or complex data samples. Samples are first mixed-down to baseband before subsequent filtering and tone detection. The centre frequency of the tone is fully programmable and is generated by a local oscillator (DDS).  The DDS has an SFDR of better than 80 dBs (with phase dithering) and a theoretical SNR of approximately 100 dBs. After down-conversion, 2 paths are filtered to remove components above the tone of interest.  The characteristics of these filters may be changed depending on the desired detection bandwidth and response time. Finally, a power function is used to compute the relative magnitude of the signal after filtering. Application Precision frequency monitoring and control FSK / OOK / ASK demodulation Touch tone decoding (e.g. DTMF tones) Complex digital down conversion   Introduction

With 18bit resolution for DAC and 18bit resolution for ADC, The IP is suitable for applications in consumer digital audio systems, automobile audio, multimedia and digital systems. Introduction
Digital Video overlay module By Quotes None 250 MHz None  
This IP is a highly versatile video multiplexer that allows one video stream to be inserted over another.  By cascading a series of video overlay modules together, any number of video sources may be multiplexed together. The module supports input video streams of any resolution or aspect ratio up to 216   x 216  pixels in size. Video overlay parameters may be changed on a frame-by-frame basis to dynamically change the size and position of the video overlay. Pixels and syncs flow in and out of the video overlay module in accordance with the valid-ready pipeline protocol. The pipeline protocol allows both input and output interfaces to be stalled independently. In addition, the overlay module supports a number of blending operations including an 8-bit alpha channel and bitwise AND, OR and XOR functions. Application Network and Tactical operations centres Digital-video special effects Broadcast TV and film production CCTV and security camera systems Introduction
2D Graphics Overlay By Quotes None 200 MHz None  
This is a highly versatile on-screen display that allows high-quality anti-aliased bitmap graphics to be inserted over RGB video. The module supports a wide range of graphics effects and the programming interface is very simple to use. The bitmap overlay is partitioned into an array of tiles which are addressed by means of an 8-bit value stored in a 64x64 tile buffer. There are four tile sizes available - either 8x8, 16x16, 32x32 or 64x64. The tiles in the buffer are displayed in a graphics window which may be positioned anywhere within the display area. Bitmaps for each tile are stored in a user-defined ROM which can contain up to  256  different bitmaps stored over three bit-planes. Depending on the chosen graphics mode, the 3-bits per pixel may be used to select one colour from a palette of eight, eight levels of alpha transparency or seven colours on a transparent background. Pixels and syncs flow in and out of the overlay module in accordance with the valid-ready pipeline protocol.
