Piranti Analog nawakake portofolio lengkap voltage solusi ngawasi, nyakup sawetara sudhut; saka saluran siji dhasar nganti multi-volume kaya fiturtage supervisor gumunggung akurasi industri-leading (nganti ± 0.3% ing suhu). Inti, I/O, lan tambahan voltage syarat kanggo macem-macem kulawarga Xilinx® FPGA resented ing tabel cetha lan gampang kanggo referensi. Inti voltage kisaran biasane span saka 0.72 V kanggo 1 V, nalika I/O voltagtingkat e bisa beda-beda antarane 1 V lan 3.3 V.

Jendhela Voltage Pengawas
Jendhela voltage supervisor digunakake kanggo mesthekake FPGAs operate ing vol amantage rentang spesifikasi.
Padha nindakake iki dening gadhah undervoltage (UV) lan overvoltage (OV) batesan lan ngasilake sinyal output reset yen ngluwihi jendhela toleransi supaya kesalahan sistem lan nyegah karusakan kanggo FPGAs lan piranti Processing liyane. Ana rong bab utama kanggo nimbang nalika milih vol jendhelatage supervisor: Toleransi lan Ambang Akurasi.
Toleransi minangka kisaran ing sekitar nilai sing diawasi nominal sing nyetel overvoltage lan undervoltage ambang. Nalika, Akurasi Ambang, biasane ditulis ing persentage, punika gelar saka conformance saka nyata kanggo batesan reset target.
Undervoltage lan overvoltage variasi ambang karo Akurasi Ambang
Milih Jendela Toleransi Tengen
Milih supervisor jendhela karo toleransi padha vol intitage requirement bisa mimpin kanggo malfunctions amarga akurasi ambang. Nyetel toleransi sing padha karo syarat operasi FPGA bisa micu output reset cedhak overvol maksimumtage ambang OV_TH (maks) lan undervol minimaltage ambang UV_TH (min). Tokoh ing ngisor iki nggambarake setelan toleransi (a) padha karo inti voltage toleransi vs (b) ing inti voltage toleransi.
Dampak saka Threshold Accuracy
Mbandhingake rong jendhela voltage supervisor karo akurasi ambang beda ngawasi vol inti padhatage rel pasokan. Supervisor kanthi akurasi ambang sing luwih dhuwur bakal nyimpang luwih sithik saka watesan ambang dibandhingake karo vol.tage supervisor karo akurasi ngisor.
Priksa gambar ing ngisor iki, pengawas jendhela kanthi akurasi sing luwih murah (a) nggawe jendhela sumber daya sing sempit amarga sinyal output reset bisa negesake ing ngendi wae ing jarak ngawasi UV lan OV. Ing aplikasi kanthi regulasi sumber daya sing ora bisa dipercaya, iki bisa nyebabake sistem sing luwih sensitif sing rawan osilasi. Ing sisih liya, pengawas kanthi akurasi ambang dhuwur (b) nggedhekake kisaran iki kanggo nyedhiyakake jangkauan operasi sing luwih aman kanggo sumber daya sing nambah kinerja sistem sakabèhé.
Power Supply Sequencing
FPGA modern nggunakake pirang-pirang voltage ril kanggo kinerja optimal. Keperluan urutan power-up lan power-down sing ditemtokake penting kanggo linuwih FPGA. Urutan sing ora bener ngenalake gangguan, kesalahan logika, lan malah karusakan permanen ing komponen FPGA sing sensitif. Piranti Analog nawakake macem-macem sirkuit pengawasan / urutan sing dirancang khusus kanggo ngatasi tantangan manajemen daya FPGA. Piranti kasebut ngatur urutan power-up lan powerdown saka macem-macem voltage ril, njamin sing saben ril tekan vol ditetepake sawijiningtage tingkat ing sawijining dibutuhake ramp wektu lan urutan. Solusi manajemen daya iki nyuda arus inrush, nyegah voltage undershoot / overshoot kahanan, lan pungkasanipun njogo integritas desain FPGA Panjenengan.
