瑞康TCXO晶振的理想方案為AI計算，Rakon今天發(fā)布了Niku，這是一款新的內(nèi)部設(shè)計的ASIC半導(dǎo)體芯片，用于超穩(wěn)定TCXOs(溫度補償晶體振蕩器)。

Niku是Rakon非常成功的冥王星的繼任者®TCXO山脈1。新平臺的首批產(chǎn)品提供了人工智能計算的基本屬性，結(jié)合了小于50飛秒的一流超低抖動、100ppb的頻率穩(wěn)定性和高達(dá)100MHz的高頻。

Rakon首席執(zhí)行官Sinan Altug博士表示，Niku的推出為該公司的人工智能計算產(chǎn)品組合奠定了基礎(chǔ)，該產(chǎn)品組合提供了使數(shù)據(jù)中心能夠滿足人工智能工作負(fù)載所產(chǎn)生的額外要求所需的性能。

“Rakon行業(yè)領(lǐng)先的技術(shù)和產(chǎn)品非常適合于克服數(shù)據(jù)中心面臨的實時并行和分布式計算的同步挑戰(zhàn)，并幫助我們的客戶釋放人工智能工作負(fù)載所需的主要性能增益，包括高帶寬可用性和超低延遲，”Altug博士說。

除了人工智能計算/數(shù)據(jù)中心，Niku產(chǎn)品還將滿足其他苛刻應(yīng)用的要求，如5G、5G Advanced和6G接入網(wǎng)絡(luò)、精確定位、汽車/V2X、工業(yè)5.0和衛(wèi)星終端。特別是定位客戶將受益于SMD振蕩器出色的穩(wěn)定性和低g靈敏度特性(0.2 ppb/g). 

Rakon超穩(wěn)定TCXOs產(chǎn)品經(jīng)理陳本表示，Niku TCXO平臺是Rakon致力于技術(shù)卓越和創(chuàng)新的證明。

“Niku產(chǎn)品路線圖承諾SMD尺寸范圍從7 x 5 mm和5 x 3 mm到3 x 2 mm，并在頻率穩(wěn)定性、進一步擴展的溫度選項和g靈敏度方面不斷進步，”Chen先生說。

所有基于Niku的振蕩器都采用了Rakon改變游戲規(guī)則的晶體MEMS振蕩器技術(shù)XMEMS®，在盡可能小的封裝中提供領(lǐng)先的振蕩器性能。XMEMS諧振器采用專有的晶圓級光刻工藝設(shè)計和制造，與傳統(tǒng)晶體諧振器相比，具有更好的g靈敏度、遲滯和頻率斜率。

除了XMEMS晶體和Niku ASIC，新的Niku產(chǎn)品還具有Rakon專有的Kelvin2溫度傳感器，使振蕩器的溫度補償更加精確。瑞康TCXO晶振的理想方案為AI計算.

New platform’s first products offer best-in-class ultra-low jitter of less than 50 femtoseconds @80 MHz.

Rakon today launched Niku™, a new in-house designed ASIC semiconductor chip for Ultra Stable TCXOs (Temperature Compensated Crystal Oscillators).

Niku is the successor to Rakon’s highly successful Pluto® TCXO range1. The new platform’s first products provide the essential attributes for AI computing, combining best-in-class ultra-low jitter of less than 50 femtoseconds with ±100 ppb frequency stability and high frequencies of up to 100 MHz.

Rakon Chief Executive, Dr Sinan Altug, says the launch of Niku lays the foundations for the company’s AI computing product portfolio, which delivers the performance needed to enable datacentres to meet the additional requirements created by AI workloads.

“Rakon’s industry-leading technology and products are ideally suited for overcoming the synchronisation challenges that datacentres face with real-time parallel and distributed computing, and help our customers unlock the major performance gains demanded by AI workloads, including high bandwidth availability and ultra-low latency,” says Dr Altug.

In addition to AI computing/ data centres, Niku products will also satisfy the requirements for other demanding applications such as 5G, 5G Advanced and 6G access networks, precision positioning, automotive/V2X, Industry 5.0 and satellite terminals. Positioning customers in particular will benefit from the oscillators’ excellent stability and low-g sensitivity behaviour (0.2 ppb/g). 

Ben Chen, Rakon’s Product Manager for Ultra Stable TCXOs says the Niku TCXO platform is a testament to Rakon’s commitment to technological excellence and innovation.

“The Niku product roadmap promises an SMD footprint range from 7 x 5 mm and 5 x 3 mm to 3 x 2 mm with continuing advances in frequency stability, further extended temperature options and g-sensitivity,” says Mr Chen.

All Niku-based oscillators feature Rakon’s game-changing crystal MEMS technology, XMEMS®, which delivers leading oscillator performance in the smallest possible package. XMEMS resonators are designed and manufactured using a proprietary wafer-level photolithographic process and offer significantly better g-sensitivity, hysteresis and frequency slope compared to traditional crystal resonators.

In addition to the XMEMS crystal and Niku ASIC, the new Niku products also feature Rakon’s proprietary Kelvin™ 2 temperature sensor, resulting in more accurate temperature compensation in the oscillator.

Rakon’s first products featuring Niku are the RTN7050A, RTN5032A and RTN5032D Ultra Stable TCXOs, with the following key specifications:
RTN7050A: SMD package: 7.0 x 5.0 x 1.5 mm | Ultra low jitter: <50 fs | Low floor noise: -170 dBc/Hz @ 38.88 MHz | High frequency: up to 100 MHz | Frequency stability: ±100 ppb over -40 to 85°C | Extended operating temperature: -40 to 105°C | Low g-sensitivity: 0.2 ppb/g | Long-term stability: ±4.6 ppm/20 yr
RTN5032A: SMD package: 5.0 x 3.2 x 1.75 mm | Ultra low jitter: <50 fs | Low floor noise: -170 dBc/Hz @ 38.88 MHz | High frequency: up to 100 MHz | Frequency stability: ±100 ppb over -40 to 85°C | Extended operating temperature: -40 to 105°C | Low g-sensitivity: 0.2 ppb/g | Long-term stability: ±4.6 ppm/20 yr
RTN5032D: Low height hermetically sealed SMD package: 5.0 x 3.2 x 1.2 mm | Ultra low jitter: <50 fs | Low floor noise: -170 dBc/Hz @ 38.88 MHz | Frequency: 10 - 50 MHz | Frequency stability: ±100 ppb over -40 to 85°C | Extended operating temperature: -55 to 105°C | Low g-sensitivity: 0.2 ppb/g | Long-term stability: ±4.6 ppm/20 yr
The launch of Niku is an important FY24 milestone for Rakon, set out in the company’s three-year growth strategy. The next product release in Rakon’s AI computing portfolio, MercuryX™, is scheduled for launch before the end of 2023 and is currently with selected customers for testing.
