Insait long ol 'high-speed data acquisition (DAQ) kad, gutpela na stretpela bilong klok signal em i bikpela samting long kisim na salim data. Ol 'differential crystal oscillators', we ol i save long en long liklik nois, strongpela 'immunity' long ol hevi, na gutpela 'stability', ol i save yusim planti long ol 'high-spid data akivisen sistem. Ol i save givim gutpela sapot long klok moa yet long ol aplikesen we i nidim bikpela 'sampling rates' na bikpela 'bandwidth'.
1. Ol gutpela samting bilong ol 'differential oscillators'
>> Low Phase Noise:I daunim 'clock jitter', na mekim gutpela 'sampling'.
>> Strongpela Anti-Interference Capability:I lukautim gut signal long longwe-transmisin na long ol ples we i gat planti nois.
>> Gutpela Signal Kwaliti:Em i gutpela long salim data i go hariap na i gat bikpela 'bandwidth', na i gutpela tru long mekim 'multi-channel synchronous sampling.
2. Ol Scenario bilong Aplikesen
I dipen long ol samting we ol kain kain intanel modul insait long wanpela hai-spid DAQ kad i nidim, ol 'differential oscillators' i save mekim bikpela wok insait long tripela bikpela samting we i stap aninit. Ol komon frikwensi tu i stap:

FPGA High-Speed Transceiver Reference Clock |
Em i givim 'reference clock' bilong ol GTH/GTX 'transceiver' insait long FPGA, we ol i save yusim long 'high-speed uplink data transmission olsem PCIe na 10 Gigabit Ethernet. |
100MHz |
• 100MHz:Standet refrens frikwensi bilong ol kompyuta bas olsem PCIe na SATA. |
|
Hai-Spid ADC/DAC Sampling Klok |
Em i makim stret 'sampling rate'. I givim ol stretpela, liklik-jitter klok arere, na mekim gutpela-konvesen long analog i go long dijitel signal. |
250MHz |
• 250MHz:Planti taim ol i save yusim long JESD204B/C hai-spid data konveta intafeis. |
|
Multi-Channel Synchronous Clock Tree |
Em i wok olsem as bilong 'clock buffer'/distributor chip insait long ol 'multi-channel acquisition cards. Bihain long distribusen, em i save kirapim olgeta ADC long wok wankain, na mekim ol i wok wankain long olgeta 'channel'. |
100MHz |
• 100MHz:Jeneral-pepos hai-presisen PLL refrens sos. |
3. Ol 'Differential Oscillators' bilong Hangjing
Ol i save yusim planti HCI diferensiel osileta long ol sistem bilong kisim ol data. Mipela i save givim ol dispela 'oscillators' long foapela sais bilong paket - 7050, 5032, 3225, na 2520 - na wantaim tripela kain autput taip - LVDS, LVPECL, na HCSL - we i givim ol fleksibel opsen long stretim ol kain kain kastoma disain rikwaemen.
HCI i ken givim ol wankain solusen na ol fri sempel. Sapos yu nidim, plis toktok wantaim 'sales' o 'technical representative' bilong yu.
