Mumakadhi e-ekukurumidza kutora data (DAQ) makadhi, kugadzikana uye kunyatsojeka kwechiratidzo chewachi kwakakosha pakutorwa kwedata uye kutapurirana. Differential crystal oscillator, anozivikanwa neruzha rwawo rwakaderera, kusadzivirirwa kwakanyanya, uye kugadzikana kwakanakisa, anoshandiswa zvakanyanya muhupamhi hwepamusoro-hurongwa hwekuwana data. Ivo vanopa yakavimbika wachi rutsigiro kunyanya mumashandisirwo anoda yakakwirira sampling mareti uye yakakwirira bandwidth.
1. Zvakanakira Differential Oscillators
>> Low Phase Noise:Inoderedza jitter yewachi, kuona-kunyatsoita sampling.
>> Kukwanisa Kudzivisa-Kupindira:Inochengetedza kutendeseka kwechiratidzo pakufamba-kureba uye munzvimbo dzine ruzha rwemagetsi.
>> High Signal Quality:Yakanakira-kufambiswa kwedata nekukurumidza uye yakakwirira-zvinoda bandwidth, zvinonyanya kuenderana-nechannel synchronous sampling.
2. Application Scenarios
Zvichienderana nezvinodiwa zvemamodule akasiyana emukati mukati me-inomhanyisa DAQ kadhi, maoscillator akasiyana anoita basa rakakosha mumatatu akakosha atsanangurwa pazasi. Common frequency anopiwa zvakare:

Technical Notes |
|
FPGA Yepamusoro-Speed Transceiver Reference Clock |
Inopa wachi yereferensi yeGTH/GTX matransceivers mukati meFPGA, inoshandiswa kukwidza{{0}speed uplink data data sePCIe ne10 Gigabit Ethernet. |
100MHz |
• 100MHz:Yakajairwa referensi frequency yemabhazi emakombuta sePCIe uye SATA. |
|
High-Speed ADC/DAC Sampling Clock |
Inogadzirisa zvakananga chiyero chekuenzanisa. Inopa micheto chaiyo, yakaderera-jitter wachi, kuona-kutendeseka kwepamusoro kubva kuanalogi kuenda kumasaini edhijitari. |
250MHz |
• 250MHz:Inowanzo shandiswa JESD204B/C yakakwirira-inomhanyisa data inoshandura nzvimbo. |
|
Multi{{0}Channel Synchronous Clock Tree |
Inoshanda semusimboti wereferensi yewachi buffer/distributor chip mune akawanda-makadhi ekutora chiteshi. Mushure mekugovera, inotyaira ese maADC kuti ashande zvakaenzana, kuve nechokwadi chekuenderana mumatanho. |
100MHz |
• 100MHz:Zvakangodaro{{0}chinangwa chepamusoro-chaizvo zve PLL referensi. |
3. Kusiyana Oscillators kubva Hangjing
HCI differential oscillators inogamuchirwa zvakanyanya mumasisitimu ekutora data. Tinopa maoscillator aya mumapasuru mana - 7050, 5032, 3225, uye 2520 - uye nemhando nhatu dzakasiyana dzekubuda - LVDS, LVPECL, uye HCSL - tichipa sarudzo dzinochinjika kuti dzienderane nezvinodiwa zvakasiyana-siyana zvekugadzira vatengi.
HCI inogona kupa mhinduro dzinoenderana uye sampuli dzemahara. Kana zvichidikanwa, ndapota taura nekutengesa kwako kwakatsaurirwa kana mumiriri wehunyanzvi.
