| Digital Down Converter with configurable Decimation Filter | 参考报价 | 无资料 | 无资料 | 无资料 |  |
|
| DDC is a complex-valued digital down-converter with a configurable number of decimation stages. The design is ideal for high sample-rate applications and permits a digital input signal to be mixed- down and re-sampled at a lower data rate. The DDC is suitable for the down-conversion of any digitally modulated signal to baseband – an essential step before digital processing. The DDC features a high-precision 16-bit DDS oscillator for the digital mixing stage. This oscillator is fully programmable and offers excellent phase and frequency resolution. The digital mixing stage is a complex multiplier that allows the mixing of both real and imaginary (I/Q) inputs. If only real inputs are required, then the imaginary input (q_in) should be tied low. The output decimation stage features a configurable decimate-by-2N poly-phase filter for both I and Q channels. Each filter stage is highly optimized to use only 12 multipliers while still achieving 80 dB of stop-band attenuation. Application Compatible with any digital modulation scheme - e.g. QPSK, BPSK, QAM, WiMAX, WCDMA, COFDM etc. Conversion of IF signals to baseband frequencies for subsequent processing Digital I/Q Demodulators | 概述 | |||||
| Binary PSK Demodulator | 参考报价 | 无资料 | 200 MHz | 无资料 | |
|
| IP is a Binary-PSK demodulator based on a multiply-filter-divide architecture. The design is robust and flexible and allows easy connectivity to an external ADC. As the the carrier recovery circuit is open-loop, there is no feedback path or loop-filter to configure. This results in an extremely simple circuit with a very fast carrier acquisition time. The only requirement is that the user set the desired symbol period and a suitable threshold level for the bit decisions at the symbol decoder. The other design parameters including carrier frequency, symbol rate and sampling frequency should be specified by the user before delivery of the IP Core 1 . The input data samples are 16-bit signed (2's complement) values that are synchronous with the system clock. Input values are sampled on the rising edge of clk when en is high.

| 10/100/1000 Ethernet Media Access Controller | 参考报价 | 无资料 | 125 MHz | 130 nm | |
|
| The MAC-1G/MAC is a synthesizable HDL core of a high-speed LAN controller. It implements Carrier Sense Multiple Access with Collision Detection (CSMA/CD) algorithms defined by the IEEE 802.3 standard for media access control over the 10Mbps, 100Mbps and 1Gbps Ethernet. Communication with an external host is implemented via a set of Control and Status Registers and the DMA controller for external shared RAM memory. For data transfers the MAC-1G/MAC operates as a DMA master. It automatically fetches from transmit data buffers and stores receive data buffers into external RAM with minimum CPU intervention. The linked list management enables the use of various memory allocation schemes. There is an interface for external dual port RAMs serving as configurable FIFO memories and there are separate memories for transmit and receive processes. Using the FIFOs additionally isolates the MAC-1G/MAC from an external host and provides resolution in case of latency of an external bus.

| JPEG Decoder | 参考报价 | 无资料 | 250 MHz | 130 nm | |
|
| This JPEG Decoder IP core has been developed to be a complete standards compliant JPEG / MJPEG Hardware Decompressor / Decoder. When decoding JPEG images, pixel throughput can not be fixed for compressed JPEGs of arbitrary quality, as it depends on the compression ratio (bits needed to encode one pixel). To circumvent this limitation JPEG Decoder IP features a dual pixel component pipeline, allowing for greater decoding speeds. | 概述 | |||||
