IC8401: 2Gbit NAND FLASH
Part number: MT29F4G08ABADAWP:D (MICRON)
Sharp code: RH-IXD552WJQZQ
Part number: MT29F4G08ABADAWP:D (MICRON)
Sharp code: RH-IXD552WJQZQ
http://datasheet.elcodis.com/pdf2/69/78/697874/mt29f4g08abadawpd.pdf
Micron NAND Flash devices include an asynchronous data interface for high-performance I/O operations. These devices use a
highly multiplexed 8-bit bus (I/Ox) to transfer commands, address, and data. There are five control signals used to implement the
asynchronous data interface: CE#, CLE, ALE, WE#, and RE#. Additional signals control hardware write protection and monitor
device status (R/B#).
This hardware interface creates a low pin-count device
with a standard pinout that remains the same from one
density to another, enabling future upgrades to higher
densities with no board redesign.
A target is the unit of memory accessed by a chip enable
signal. A target contains one or more NAND Flash die. A
NAND Flash die is the minimum unit that can
independently execute commands and report status. A
NAND Flash die, in the ONFI specification, is referred to
as a logical unit (LUN). There is at least one NAND Flash
die per chip enable signal. For further details, see Device
and Array Organization.
This device has an internal 4-bit ECC that can be enabled
using the GET/SET features.
These devices use NAND Flash electrical and command
interfaces. Data, commands, and addresses are multiplexed onto the same pins and received by I/O control circuits. The
commands received at the I/O control circuits are latched by a command register and are transferred to control logic circuits for
generating internal signals to control device operations. The addresses are latched by an address register and sent to a row
decoder to select a row address or to a column decoder to select a column address. Data is transferred to or from the NAND
Flash memory array, byte by byte (x8) or word by word (x16), through a data register and a cache register. The NAND Flash
memory array is programmed and read using page-based operations and is erased using block-based operations. During normal
page operations, the data and cache registers act as a single register. During cache operations, the data and cache registers
operate independently to increase data throughput. The status register reports the status of die operations.
IC9501: Single Port 10/100 Fast Ethernet Transceiver
Part number: KSZ8081RNDTR (MICREL)
Sharp code: RH-IXD543WJZZY
http://www.mouser.com/catalog/specsheets/KSZ8081RNDCA.pdf
The KSZ8081RND is a single-supply 10BaseT-100Base-TX Ethernet physical-layer transceiver for transmission and reception
of data over standard CAT-5 unshielded twisted pair (UTP) cable.
The KSZ8081 is a highly-integrated PHY solution. It reduces board cost and simplifies board layout by using on-chip
termination resistors for the differential pairs and by integrating a low-noise regulator to supply the 1.2V core, and by offering
1.8/2.5/3.3V digital I/O interface support.
The KSZ8081RND offers the Reduced Media Independent Interface (RMII) for direct connection to RMII-compliant MACs in
Ethernet processors and switches
As the power-up default, the KSZ8081RND uses a 25MHz crystal to generate all required clocks, including the 50MHz RMII
reference clock output for the MAC.

IC1106: Silicon Tuner (Analog & DVB-T/C/T2)
Part number: Si2178-A20-GMR (SILICON LABS)
Sharp code: RH-IXD518WJZZY
http://www.silabs.com/Support%20Documents/TechnicalDocs/Si2178-short.pdf
The Si2178 integrates a PAL/SECAM/NTSC analog TV demodulator with a universal hybrid TV tuner supporting all worldwide
digital and analog TV standards. The Si2178 requires no external balun and offers the lowest-cost BOM for a hybrid TV tuner
with analog demodulator. By combining Silicon Labs' proven digital low-IF architecture with a 4th-generation RF front-end, the
Si2178 maintains the highest performance that exceeds MOPLL-based tuners, including industry-leading 2nd-order distortion
performance.
Compared with competing silicon TV tuners, the Si2178 delivers an unprecedented level of front-end integration, resulting in the
lowest number of external BOM components. No external tracking filters, wire-wound inductors, LNAs, SAW filters or
inductive power supply filtering components are needed. The Si2178 offers low power consumption as well as an option for
single or dual power supply operation. Also included is an internal power-on reset circuit, eliminating the need for external
brownout protection components or additional pins in module applications.

For next-generation digital TV broadcast standards, such as DVB-T2 and DVB-C2, that are sensitive to integrated phase noise,
the Si2178 offers industry-leading phase noise performance. A software-selectable cable mode is also included which offers high
return-loss performance.

incorporate worldwide field testing experience from three previous generations in high-volume production, to deliver the highest
tolerance to real-world field reception conditions. The Si2178 also incorporates a harmonic-rejection mixer that delivers
excellent immunity to Wi-Fi and LTE interference across the full RF input frequency range, with no need for external filtering
components.

IC1102: DVB-T/C Demodulator.
Part number: Si2165-D-GMR (SILICON LABS)
Sharp code: RH-IXD519WJZZY
Part number: Si2165-D-GMR (SILICON LABS)
Sharp code: RH-IXD519WJZZY
http://www.silabs.com/Support%20Documents/TechnicalDocs/Si2165-short.pdf
The Si2165 is a compact standalone DVB-T/C digital TV. The analog front-end consists of two ADCs with wide dynamic range
(12-bit) to allow operation with standard IF (~36 MHz), Low-IF, or Zero-IF inputs. This enables the use of the Si2165 with any
TV tuner, either metal can or silicon tuner based.
The multi-standard demodulator supports all modes of DVB-T (EN 300 744), including hierarchical modes. The Si2165 also
supports ITU J.83 annex A/C and DVB-C (EN 300 429), including a user-configurable 31-tap equalizer. In addition to DVB-T's
legacy modes, the Si2165 also complies with DVB-H (EN 300 744 Annex F) specificities: 4K FFT, extended TPS, “native” and
“in-depth” de-interleavers. The Si2165 is able to receive DVB-H programs in fixed receiver applications (without decoding the
additional MPE FEC layer).
An embedded 32-bit DSP controls device operation. Sophisticated on-chip algorithms ensure optimum reception even under
difficult channel conditions, such as echoes outside the guard interval, pre-echoes, or strong impulse noise. For ease-of-use, DSP
firmware is preloaded into ROM (device is immediately active at power-up). Nevertheless, there is a possibility of downloading
additional patch code via the I2C interface (e.g., to adjust the demodulator to unexpected conditions or reception impairments).
Thanks to proprietary features, the Si2165 supports ultra-fast channel scanning for VHF/UHF terrestrial and cable DTV
channels. For supported tuners, the Quickscan algorithm for blindscan is running onto the embedded DSP (in order to limit the
host CPU load) and is provided as a downloadable patch file.
Serial or parallel master MPEG TS output modes are supported. Furthermore, a TS slave parallel mode is available via a GPIF
port and provides a glueless interface to Silicon Labs' MCU devices with embedded USB interface. The user can optionally
program a 32-PID hardware filter to reduce the output TS bit rate.
An internal I2C pass-through logic switch acts as an I2C repeater. This provides a “quiet” I2C bus to the RF front end.
A maximum of six general-purpose inputs/outputs are available; three GPIOs also feature
Δ/Σ and interrupt output capabilities.
Best-in-class demodulation performance is achieved while still maintaining very low-power operation.
The Si2165 guarantees a low-cost system implementation due to its minimal BOM and very small package footprint.
