The CML driver is specifically designed for a clock distribution network for high speed signaling. A bias current is necessary to bias the current sources in the CML driver. The biasing circuitry can be amortized over multiple drivers to minimize the overhead. The device operates from 0.9-V to 1.1-V supply environment and is characterized from –40°C to 125°C. The CML driver employs a fully differential structure in order to maximize the rejection capabilities against common-mode noise and power supply noise. The CML driver has been experimentally verified through its application in LPDDR5 DRAM interface. 2025-06-24 Repeater Chain The Repeater Chain IP is a mixed-signal, high-speed, low-power signal conditioning block designed to restore signal quality across long on-chip interconnects. It consists of a cascaded buffer/inverter architecture that compensates for RC-induced delay and waveform degradation, ensuring clean and reliable digital signal propagation over extended wire lengths. The core employs a multi-stage structure of optimally sized CMOS repeaters, each regenerating the signal and sharpening its transition edges. Input and output are both standard digital logic levels, with the output exhibiting enhanced edge rate and minimized delay skew. The number and placement of repeater stages are tuned based on wire length, capacitive loading, and timing constraints. To support robust operation under process, voltage, and temperature (PVT) variations, the IP optionally integrates control logic for dynamic drive strength adaptation. This ensures consistent performance across corner cases without requiring external calibration. Designed for integration in global SoC routing paths, clock distribution trees, and high-speed data buses, the Repeater Chain IP provides an essential solution for maintaining signal integrity and timing reliability in advanced digital systems. Figure 1 shows the functional block diagram of the repeater chain, including the parasitic load capacitance from the metal line. Implemented in a 28nm standard CMOS process with minimal area and power overhead, it is well suited for power-conscious, high-performance applications. 2025-06-24 Input Clock Buffer This digital buffer takes CMOS level input and generates CMOS level output. It achieves high power efficiency, low rise-fall skew, and moderate noise level. Figure 1 shows a functional block diagram of the buffer. Four inputs (in0 ~ in3) are respectively buffered. 2025-06-24 Frequency Divider Figure 1 shows the functional block diagram of the frequency divider. It receives two complementary CMOS-level inputs, WCLK and WCLKB. When DIVEN is high, the block generates four-phase quadrature CMOS-level outputs: ICLK, QCLK, IBCLK, and QBCLK. When AFEN is high, a delayed version of ICLK, labeled ICLK_AF, is also provided. VLDO denotes the supply voltage of the block. 2025-06-24 처음으로 이전페이지 6 7 8 9 10 11 12 13 14 15 >다음페이지 마지막으로
