Component Details

Processor

RK3399 is a low power, high performance processor for computing, personal mobile internet devices and digital multimedia devices; it integrates dual-core Cortex-A72 and quad-core Cortex-A53. RK3399 supports multi-format video decoders including H.264/H.265/VP9 up to 4Kx2K@60fps, especially, H.264/H.265 decoders support 10bits coding, and also supports H.264/MVC/VP8 encoders by 1080p@30fps, high-quality JPEG encoder/decoder, and special image preprocessor and postprocessor. RK3399 has high-performance dual channel external memory interface (2x32bit LPDDR3) capable of sustaining demanding memory bandwidths. Learn more at RK3399 Product Page.

PMIC

The PMIC on ROCK960 is RK808-D, a companion PMIC for RK3399 by Rockchip.

The RK808-D is a complete power supply solution for portable systems. The highly integrated device includes four buck DC-DC converters, three high performance ldos, I2C interface, programmable power sequencing and an RTC.

The RK808-D improves performance, reduces component count and size, and therefore provides lower cost solution compared to conventional portable designs. The ultra fast 2MHz current mode DC/DC architecture optimizes the transient performance and is compatible with tiny low cost ceramic inductors and capacitors. All DC/DC channels include integrated MOSFETS. Internal soft-start and compensation circuits minimize external components count. Most outputs can be programmed through the I2C interface

The RK808-D integrates internal RC oscillator for low cost application which without RTC function.

Memory (DRAM)

The ROCK960 Board provides 1GB(model C1) or 2GB(model C2) or 4GB(model C4) LPDDR4-SDRAM which is a 2-channel and 32bit width bus implementation interfacing directly to the RK3399 build-in LPDDR controller. The maximum DDR clock is 800MHz. It’s soldered on board and not replaceable.

Storage

The ROCK960 Board doesn’t provide any on board storage, it reserve a eMMC socket for flexible storage options.

eMMC Socket

The eMMC socket uses two B2B connector to mount the eMMC module, the connector model is GB042 Series, one connector(34pin) for eMMC signal, the other(30pin) is for mount purpose only.

  • on board: GB042-34S-H10 (socket-34pin) + GB042-30S-H10 (socket-30pin)
  • on eMMC module: GB042-34P-H10 (Plug-34pin) + GB042-30P-H10 (Plug-30pin)

Micro SDHC

The ROCK960 Board SD slot signals are routed directly to the RK3399 SDIO interface. It meets the SD3.0 standard.

Boot ROM

The ROCK960 Board can boot up from the EMMC or the Micro SD card. If a bootable Micro SD card is inserted, ROCK960 will boot from Micro SD card and ignore the EMMC. If the Micro SD card is not inserted or non-bootable(ie. as storage media). The ROCK960 will try to boot from EMMC. If there is no bootable image in EMMC, the board will go to Maskrom mode and wait for USB command from host.

Networking

WiFi

The wifi/bt module used on ROCK960 model C is AP6255 from AMPAK Technology. The AP6255 module complies with IEEE 802.11 a/b/g/n/ac standard and it can achieve up to a speed of 433.3Mbps in 802.11n to connect the wireless LAN.

  • 802.11a/b/g/n/ac dual-band radio with virtual-simultaneous dual-band operation
  • Single-stream spatial multiplexing up to 433.3 Mbps data rate.
  • Supports 20, 40, 80 MHz channels with optional SGI(256 QAM modulation)
  • Supports standard SDIO v3.0 and backward compatible with SDIO v2.0 host interfaces.

The ROCK960 Board also has a RF connector to connect the external antenna or other RF device. If you want to use this function, you should change the 0ohm resistor directions besides the antenna.

Bluetooth

  • Supports Bluetooth V4.2+EDR with integrated PA for Class 1.5 and Low Energy (BLE).
  • Concurrent Bluetooth, and WLAN operation.
  • Simultaneous BT/WLAN receive with single antenna.

Display Interface

HDMI

RK3399 support HDMI 1.4 and 2.0, up to 10-bit depth color mode, up to 1080p at 120Hz and 4Kx2K at 60Hz HDTV display resolutions and up to QXGA graphic display resolutions.

MIPI-DSI

  • The 96Boards specification calls for a MIPI-DSI implementation via the High Speed Expansion Connector.
  • The ROCK960 Board implements a 4-lane MIPI_DSI interface meeting this requirement. It can support up to FHD(1080p@60fps). The ROCK960 Board routes the MIPI_DSI interface signals to the MIPI_TX interface of the RK3399.

Camera Interface

  • The 96Boards specification calls for two camera interfaces.
  • The ROCK960 Board supports two camera interfaces, one with a 4-lane MIPI_CSI interface and one with 2-lane MIPI_CSI interface, meeting this requirement. The 4-lane MIPI_CSI interface routes to MIPI_TX/RX of RK3399, it can also be configured as MIPI_DSI.

USB Ports

The RK3399 has one USB 3.0 HOST controller, one USB 3.0 OTG controller, two USB 2.0 HOST controller, the four USB controllers can work independently, they are implemented on ROCK960 as following:

USB Host

  • USB3 HOST1 routes to USB 3.0 type A(next to mounting hole onboard)
  • USB3 OTG routes to USB 3.0 OTG with Type A connector(in the middle)
  • USB 2.0 HOST0 as USB 2.0 with Type C connector(next to HDMI connector)
  • USB 2.0 HOST1 on the high speed expansion header

The USB 3.0 OTG can work in device mode or host mode. There is an on board switch to switch the OTG as Host or device mode. In maskrom mode, the OTG is forced in device mode.

When USB 3.0 OTG in device mode, you need a USB A-to-A cable connects to PC or host computer.

Audio

The ROCK960 Board has two audio ports: HDMI, I2S.

DC Power

The ROCK960 Board can be powered by two ways:

  • 8V to 18V supply from a dedicated DC jack

The 96Boards specification calls for three power rails to be present on the Low Speed Expansion Connector:

  • +1.8V Max of 100mA
  • +5V Provide a minimum of 5W of power (1A).

SYS_DCIN 8-18V input with enough current to support all the board functions or the output DCIN from on-board DC Connector able to provide a minimum of 7W of power.

The ROCK960 Board supports these requirements as follows:

  • +1.8V Driven by PMIC RK805 up to 2500mA. It is the system main 1.8V power (VCC_1V8), and it can supply power up to 200mA to the Low Speed Expansion Connector.
