ChipX在其IP陣容中新增10位元、210Msps的DAC家族(英文內容)
(技術新聞, 2008年7月3日)

ChipX Inc. has announced the addition of a family of 10-bit, 210Msps current steering DACs to its extensive line-up of analog and mixed-signal IP. Designed for high speed applications, the single, dual, triple and multi-channel ChipX DACs are ideal for system-chip designs used in component (RGB) or composite video encoding, WiMAX or 802.11 front-ends, and a variety of medical and industrial products. Fully characterized in high-volume process technologies of ChipX foundry partners, the DACs can be combined with other proven ChipX communications, memory and microcontroller IP for System-on-Chip designs.
Conversion speeds from DC to 210Msps are achievable in 130nm depending on configuration. Multi-channel (two or more) solutions can share resources, such as the built-in reference source, to optimize space and power requirements, or have individual references for design flexibility. The DACs are capable of driving up to 34.5mA per channel into 75¦¸ differential terminations, for 1.2V level signals compatible with most video standards. Subjective image tests show a significant improvement when comparing a standard test image displayed by the ChipX DAC to a standard PC graphics card, in the same resolution.
In addition to a small die area the DACs support a variety of power limiting technologies to achieve typical active power consumption of 120mW per channel at maximum frequency, 10mW in standby mode and 4µW in power down mode. Applications requiring less than the maximum drive strength can conserve significant power by changing a single reference resistor.
Each of the DAC family members includes reference circuits, simple processor interface, and output buffers, and a demonstration platform is available on request. They can be integrated with the full range of ChipX building blocks—including USB 2.0, PCI Express, DDR/DDR2, ARM(926) or BA12/22 processors to create a System on Chip (SoC)—in mixed-signal Hybrid ASIC, Embedded Array or Standard Cell products.
