I'm trying to build a microcontroller based FM transmitter which can change frequencies on the fly (88 - 108 Mhz) and is able to transmit 20-30 meters to cover my house. I am looking at DigiKey's web site right now and I am wondering which Si570 CMOS chip I should order for this project. gbic是将千兆位电信号转换为光信号的接口器件。gbic设计上可以为热插拔使用。gbic是一种符合国际标准的可互换产品。. המוצר גבישים, מתנדים, מהודים - מתנדים קיים במלאי אצל DigiKey. 156mhzのMCLKで聴いてみるとやはり聴感上違いがあります。11. After the first mixer, there is again an amplifier in order to have a broadband termination for the mixer. Circuitry is also provided to utilize the on-chip squarer and frequency doubler to produce square waves up to 800 Mhz. Order today, ships today. As can be seen, the Si570 requires a minimum number of external components in this application. Q1 through Q4 are BS170FTA N-channel MOSFETs in SOT23-3 SMD package, Digikey PN BS170FCT-ND. なので、Mouser 、NEWARK、Digi-Key、RF PARTS、MINI-KITS、更には、秋月電子など6社以上を総動員して在庫のあるディストリビューターで手配する。 Mouser 以外は、規定の金額に達してない為に国際郵便の送料まで取られて・・部品代よりも送料が高い!. So the drive has been reduced to a nice square wave about 1 volt PTP for each channel Just to the right of the BPF and to the left of the ADE-1's is a hybrid combiner transformer. In Sachen "SI570" und Relais werde ich in den nächsten Tagen erneut eine Sammelbestellaktion starten: diesmal ist DIGIKEY dran. With the idea that driving the FIFO from an arm raspberry pi/beaglebone it would make sense to control the si570 from the same device. If it is a multiple of some common frequency then I would expect it to be specified with 3 digits like 32. 8″ ExpressPCB MiniBoards. Le Si570 est un VCXO piloté par I2C, commun à beaucoup de tranceiver SDR de type « conversion directe » de première génération. # Enable PHYLIB and NETWORK_PHY_TIMESTAMPING to see the additional clocks. 3V ±10%, TA = –40 to +85 oC Parameter Symbol Test Condition Min Typ Max Unit CMOS Output Logic. [6],: CMOS bis 160 MHz, LVDS bis 215 MHz und VPECL bis 810 MHz. It covers the frequency range from 100 kHz to 170 MHz (or in some cases, 250 MHz). 11 and up from digikey. Pops QRPHomebuilder - Free ebook download as PDF File (. I have acquired an old Midland 13-509 220 MHz band transceiver. Det sjoveste er jo det man ikke ved noget om, og på den måde lære noget, det er jo derfor man kalder sig amatør. The trimmer caps can be the 5 - 20 pF units sold by Digi-key and Mouser. SiLabs 570CAC000141DG part ) The oscillator itself is pretty simple, and is the bare essential hardware required for re-programming the oscillator for a needed single frequency to use with a Softrock Lite II rx. Block Diagram The block diagram of the KCU1500 data center board is shown in. Der mcHF ist eine Entwicklung von Chris, Rufzeichen M0NKA, und wurde maßgeblich durch die Softrock und SDRCube Projekte beeinflusst. о других компонентах - FPGA EP3C25-PQFP240 (Altera Cyclone III), CY7C68013A, а также Si570 ссылок о продаже очень много. The Analyzer Calibration can be done with the two switches. with temperature, humidity, or due to dust on the circuit board. Note that maximum LO drive to the AD831 should not exceed 1 Vp-p. The least expensive I found was either LVDS or LVPECL type for this frequency. 3 V CMOS) at 144 MHz to drive a small class E amplifier. Crystal, XO (Standard), 8-SMD, No Lead. 购买后,将显示帖子中所有出售内容。. DigiKey P10859-ND Rotary Encoder (or equivalent) IN COM OUT 7805 +12 V DC +5 V DC 4. com 2 UG954 (v1. Zależnie od wersji ma 3 lub 8 niezależnych wyjść. The 500 MHz clock on that DDS kind of limits your output freq to about 200 MHz, so it wouldn't be much use at UHF. Support is also provided for the Si570 programmable crystal oscillator. DigiKey에서 수정, 발진기, 공진기 - 발진기 제품을 보유하고 있습니다. com web site. 55€ bei DigiKey), dessen Rauschkurve je-doch recht steil abfällt und bei 3kHz Abstand bereits -130dB erreicht. In loser Folge werde ich an dieser Stelle meine Erfahrungen beim Aufbau des mcHF QRP-Transceivers Version 0. 部品の即日出荷なら、Digi-Keyにお任せ! 570BAB000544DGR – 156. 2 and 1500 MHz. Pricing and Availability on millions of electronic components from Digi-Key Electronics. To use the Ensemble with the Teensy SDR code you pull out the Tiny AVR chip and connect the SI570 SDA and SCL signals directly to the Teensy I2C bus. Compare 570CAC000121DG price and availability by authorized and independent electronic component distributors. kein REI Seite 1 Pos. Order today, ships today. Silicon Labs. Instead of using multiple Si570's, would it be possible to use a single Si5351? The 5351A has 3 outputs and provides a different frequency on each of those outputs, meaning that a single chip could provide both the VFO and BFO signal. Buzz around the Si5351 has been picking up at a pretty rapid clip over the last month or so, but a lot of homebrewers have been hesitant to use it in their designs because one critical parameter has not yet been measured: phase noise. Ethernet to Radio Adapter. (Other versions of the Si570 can go up to 1. The 500 MHz clock on that DDS kind of limits your output freq to about 200 MHz, so it wouldn't be much use at UHF. Order Now! Crystals, Oscillators, Resonators ship same day. The day after, I started to solder a large part of the SDR transceiver, but unfortunately, I missed the CODEC in my components order…. U1 & U2 are Silicon Labs Si570 I2C Programmable XO/DSPLL type CCC000107G, per the discussion above. This allows the AD831 to be driven directly by the Si570 XO/DSPLL with only a voltage divider to set the correct drive level. 5V Enable/Disable (Reprogrammable) 8-SMD, No Lead from Silicon Labs. Contribute to sparkfun/SparkFun-Eagle-Libraries development by creating an account on GitHub. I measured every resistor before soldering and took great care not to make any mistakes along the way. com web site. One button push on the tuner and the Z-817H takes care of the rest.
