Main components & that RJ45 jack

The two main PCB components are as follows. Due to NDA and proprietary issues the Broadcom chipset, all I could find was a PR announcement for the 2015 CES (no less).

Broadcom BCM4554 Full-Band Capture Satellite Channel Stacker Solution

2015 Consumer Electronics Show (CES);
Broadcom announced a new low-power satellite device in its Outdoor Unit (ODU) portfolio. The BCM4554 addresses consumer demand for satellite services with support for North America, Europe and Asia-Pacific regions.

The new device adds support for up to 32 resident set-top boxes (STBs) on a single coaxial cable within a multiple dwelling unit, enabling operators to deliver additional services to more subscribers without requiring new satellite dish installations. These offerings also enable operators to improve services such as faster channel changing by assigning more channels to a single STB.

"Broadcom's newest addition to our low-power ODU portfolio allowsb operators to increase the availability of satellite services in single homes and multiple dwelling units across the globe," said Nicholas Dunn, Broadcom Vice President of Marketing, Broadband & Connectivity Group. "The BCM4554 enables operators to streamline the cabling, hardware and installation costs associated with supporting multiple set-top-boxes and ultimately simplify satellite distribution to their customers."

Among residential customers worldwide, access to free-to-air channels provided by a range of satellites has stimulated demand for satellite TV. In order to lessen deployment costs resulting from the need for separate coaxial cables for each STB, Broadcom's BCM4554 device simplifies installation for these additional service offerings.

Broadcom's BCM4554 offers a higher level of integration while consuming less power than the previous generation chipset. It also enables direct sampling of low-noise block (LNB) outputs across worldwide ODU satellite markets. The simplified design of Broadcom's new ODU chipset allows 32 DVB-S2 channels to be stacked on a single coaxial cable to service any STB in a home, simplifying and reducing satellite operator installation costs.

Broadcom's BCM4550 satellite channel stacker solution is a fully integrated satellite Outdoor Unit (ODU) solution to support Full-Band Capture (FBC) technology. Broadcom's BCM4550 with integrated Full-Band Capture digital-tuning technology minimizes satellite TV installation costs and complexity, delivering single-wire architecture into the home. Enabling design efficiency and scalable bandwidth to operators, Broadcom's ODU technology provides a TV-everywhere connected home experience with additional high-definition video streams, multiroom DVR and IP services.

Microchip PIC18F8750 64/80-Pin High-Performance, 1-Mbit Flash USB Microcontrollers w nanoWatt Technology

The PIC18F87J50 microcontroller is the “superset” device in the PIC18F87J50 micro-controller family. The PIC18F87J50 has the highest memory and pin count in the family, but otherwise shares an identical feature set (except features which require pins not present on 64-pin devices) compared to the other devices. All of the devices in the family are code-compatible with each other and share the same USB capabilities:
• USB 2.0 compliance
• Full-speed (12 Mbit/s) and low-speed (1.5 Mbit/s) operation
• Support of control, interrupt, bulk and isochronous transfers
• Support of up to 32 endpoints
• 3.9 Kbytes of dual access RAM for USB or general purpose use
• On-chip features for a single chip USB implementation, including:
- USB Serial Interface Engine (SIE)
- USB transceiver
- USB pull-up resistors
- D+ and D- driver output impedance matching resistors

Separate subject;

That RJ45 jack on the device, it can only be used for their handheld programing unit. Of course I did ask about that also. The response was basically cost to implement it. They wanted to keep the cost down as much as possible, so that was passed by.

I don't know the protocol that is used, but I wonder if an outboard Network adapter couldn't be designed (if there isn't anything already) to 'adopt' it for Network use so one could control the functions from desktop or Laptop PC? That would be separate from the unit as an option.
Keep OTA television alive. Streaming is 'all wet'..........
