{{>toc}} h1. [[PageOutline]] = HSL Femtocell Hardware *NOTE: = '''NOTE: All information on this website is gathered on our own, without any cooperation of the manufacturer. There is no guarantee of correctness. There is no relationship between HSL and the [[OpenBSC]] OpenBSC project developers! h2. == Overview == The HSL femtocell hardware consists of two boards: A digital board with the ARM, DSP and FPGA, as well as the radio board, containing the ADC/DAC/oscillator/mixer/filter/duplexer. Both boards are interconnected using a small adapter board. This adapter board also contains the Ethernet jack (including magnetics). h2. == Digital Board == The digital board contains a placement option for a GPS module [[Image(hsl_femto_digital_pcb.jpg)]] h3. === Main Processor === * TI [[DaVinci]] DaVinci ARM+DSP (TMS320DM6443A) ** * http://focus.ti.com/docs/prod/folders/print/tms320dm6443.html ** * http://focus.ti.com/lit/ds/sprs282g/sprs282g.pdf h3. === FPGA === * Xilinx Spartan-3A DSP FPGA (XC3SD1800A) ** * http://www.xilinx.com/onlinestore/silicon/online_store_s3a.htm ** * http://www.xilinx.com/support/documentation/data_sheets/ds610.pdf h3. === Power Management === * TI TPS65023 6-channel PMIC (TPS65023) ** * http://focus.ti.com/docs/prod/folders/print/tps65023.html ** * http://www.ti.com/lit/gpn/tps65023 * TI 3-6V 3A synchronous step down SWIFT converter TPS54310 ** * http://focus.ti.com/docs/prod/folders/print/tps54310.html ** * http://www.ti.com/lit/gpn/tps54310 h3. === Ethernet MAC === * Realtek Ethernet MAC (RTL8201BL) ** * http://realtek.info/pdf/rtl8201bl.pdf h3. === Memory === * 2x Micron DDR2, 512Mbit, 0HF12 D9JLR C26V (MT47H32M16HR-3:F) *** * 84pin FBGA package, 1.8V *** * http://www.micron.com/get-document/?documentId=455&file=512MbDDR2.pdf * ST Micro 1Gbit NAND Flash NAND01GW3B2CZA6 ** * http://pdf1.alldatasheet.com/datasheet-pdf/view/131765/STMICROELECTRONICS/NAND01GW3B.html h3. === Miscellaneous === * 2x TI Voltage translation for the bus (sn74avcb164245) ** * http://focus.ti.com/lit/ds/symlink/sn74avcb164245.pdf h2. == RF board == So far we have only documented those parts that are not under the massive shielding cover.
