| The Serial Peripheral Interface (SPI) bus, established by Motorola, is a synchronous serial data link. It operates in master/slave and full duplex styles. That is, when a master device initiates a transaction and communicates with a certain slave device, they exchange data bit-by-bit. Furthermore, the single master communication is applied to the SPI bus. Thus, there is always a single master device (with one or more slave devices) on it. The SPI bus contains 4 wires, with each named SCK, MOSI, MISO and SS_n respectively. You may also find alternative naming conventions elsewhere. The following table lists their functions and directions: The typical SPI bus architecture is designed as follows: When the SPI master device wants to communicate with a certain slave device, it asserts the SS_n line of that slave device, and then exchange data using the MOSI and MISO lines based on the toggling SCK line. With clock polarity (CPOL) and clock phase (CPHA) set to different values, the SPI bus can operate in 4 modes. These modes are listed in the following table, where provide means that the communicating master and slave devices provide data on the MOSI and MISO lines respectively on the other hand, capture means that the communicating master and slave devices capture data on the MISO and MOSI lines respectively: | 概述 | |||||
| 10-bit 300 MSPS Video DAC IP in 90 nm | 60000 点 | 76.000 K μm^2 | 300 MHz | 90 nm | |

| The UIP_DAC10-300M_205370 is a 10-bit DAC designed in low power TSMC 90 nm logic process. It consists of a current steering DAC. The DAC uses a fully differential architecture. The input data of the DAC is in 1.2V, in unsigned format. A 3.3V supply is used for the analog portion of the IP. This high performance DAC is designed for CVBS standard or RGB Video signal bandwidth. The IP consumes only 41 mA at 300 MSPS operation and utilizes a silicon area of only 0.076 mm2. The IP does not require any external decoupling and is ideal for integration in mixed-signal systems. The DAC output current is 6-bit programmable. The IP architecture is robust and can be ported to other 90 nm processes. APPLICATIONS Composite Video (CVBS) HDTV RGB Video DAC Output Model | 概述 | |||||

| Video Frame Buffer | 参考报价 | 无资料 | 300 MHz | 无资料 | |
|
| VID_FB is a high-speed multi-format video frame buffer that asynchronously samples an input video stream and buffers it in an external memory. Output pixels are read out of the buffer and synchronised to the system clock domain. The VID_FB will automatically adapt to different input and output frame rates. If the input frame rate is too high, then the VID_FB will cleanly drop or 'skip' an input frame. Likewise, if the output frame rate is higher than the input frame rate, then frames will be repeated 3 . The result is a system that seamlessly adapts to the different frame rates at the input and output of the VID_FB.

| FIR filter | 参考报价 | 无资料 | 300 MHz | 无资料 | |

| FIR_F is an FIR filter implementation designed for very high sample rate applications. Organized as a systolic array the filter is modular and fully scalable, permitting the user to specify large order filters without compromising maximum attainable clock-speed. Mathematically, the filter implements the difference equation: y[n] = h0 x[n] + h1 x[n−1] + ... + hN x[n−N ] In the above equation, the input signal is x[n], the output signal is y[n] and h0 to hN represent the filter coefficients. The number N is the filter order, the number of filter taps being equal to N+1.

| Half-band Nyquist decimation filter | 参考报价 | 无资料 | 300 MHz | 无资料 | |

| The IP is an N-channel multiplexed FIR filter designed for high sample rate applications where hardware resources are limited. The main filter core is organized as a scalable systolic array permitting the user to specify large order filters without compromising maximum attainable clock-speed. Essentially the filter functions as if it were 'N' separate FIR filters. Each input sample is multiplexed into the filter at a sample rate equal to Fs /N, where Fs is the sampling frequency of the main filter core. Likewise, output samples are updated at a frequency of Fs /N. The first sample into the filter is aligned by asserting the signal X_VALID high. The signal Y_VALID_val is asserted with the first valid output sample. Data samples are advanced in the pipeline on the rising clock-edge of clk when en is active high. When en is low then all data samples are stalled. The clock-enable signal may be used to temporarily disable the filter - or possibly to modify the effective sampling frequency of the system clock. If the clock-enable is not needed it is recommended that this signal be tied high as it will improve overall circuit performance.
