Broadcom Corp. announced on April 25, 1999, that it planned to acquire Epigram Inc. for 4.6 million Broadcom Class B common shares. EE Times reported the proposed consideration at approximately $315 million, based on Broadcom’s closing share price on Friday, April 23. The deal was designed to add phone-line home-networking technology to Broadcom’s cable-modem and DSL chip business, but the contemporaneous report does not independently confirm that the transaction closed or that Epigram’s products reached volume production.
What Broadcom announced
Broadcom’s announcement was made Sunday, April 25, 1999, and reported by EE Times on Monday, April 26. The buyer said it would acquire Epigram, a semiconductor startup developing controllers for networking inside homes. The proposed consideration was 4.6 million Broadcom Class B shares.
The reported value of about $315 million was an equity-market calculation, not a stated cash price. It used Broadcom’s closing stock price from the preceding Friday, so the implied value would have moved with Broadcom’s share price unless the agreement contained additional terms not described in the report. Contemporaneous coverage in EE Times is the source for these transaction details.
What Epigram was building
Founded in 1996, Epigram was developing controllers that carried network traffic over the twisted-pair telephone wiring already installed in many houses. Its designs were derived from Ethernet media-access-control technology, but the physical connection was the home’s phone wiring rather than newly installed Ethernet cable.

iLine 10 development status
Epigram had demonstrated prototypes of its first iLine 10 chipset at the previous fall’s Comdex and had begun sampling devices in March 1999. Those milestones show an active chip-development and customer-sampling program; they do not establish volume manufacturing, retail availability, throughput, range, or commercial success.
The report described Epigram as being ahead of competitors including Conexant Systems Inc. and Advanced Micro Devices Inc. That was the contemporary publication’s characterization, not an independently verified performance ranking.

Why phone-line networking mattered in 1999
Cable modems and DSL were expanding broadband access to the home, but a connection from an outside network did not automatically connect several PCs, appliances, or consumer-electronics devices inside the house. Running new network cable through existing homes could be expensive or impractical.

Broadcom president Henry Nicholas described the intended opportunity as delivering voice, data, and video to network-enabled appliances, PCs, and consumer-electronics devices over ordinary phone lines. That statement described the strategic objective at announcement time, not a documented later outcome.
Rank #3
- Dual band router upgrades to 1200 Mbps high speed internet (300mbps for 2.4GHz plus 900Mbps for 5GHz), reducing buffering and ideal for 4K stream
- Full Gigabit Ports - Gigabit Router with 4 Gigabit LAN ports, ideal for any internet plan and allow you to directly connect your wired devices

- MU-MIMO technology - (5GHz band) allows high speeds for multiple devices simultaneously
- Access Point Mode - Supports AP Mode to transform your wired connection into wireless network, an ideal wireless router for home
What the technology was—and was not
- It was wired networking over existing telephone pairs.
- It was not Wi-Fi, a consumer internet-service plan, or a finished retail router brand.
- It addressed distribution of connectivity within a home after broadband access arrived through cable or DSL.
How the proposed deal fit Broadcom
Broadcom was already a mixed-signal and digital-signal-processing chip supplier focused on broadband-access technologies, including cable-modem and DSL systems. Epigram’s controllers were strategically adjacent: Broadcom could potentially participate both in bringing broadband into the home and in distributing that connection among devices inside it.
Buying a specialist could also provide a faster route to market than creating a phone-line architecture internally, while adding Epigram’s engineering team and its work with industry partners. These are reasonable strategic inferences from the reported facts, not documented promises that the combined company achieved those goals.

Planned organization
Epigram president and chief executive Jeff Thurmond was expected to become general manager of Broadcom’s new home-networking division. The announcement establishes the planned reporting arrangement; it does not establish how long Thurmond held that position.

Minority investors
The report identified Panasonic and 3Com as minority equity holders in Epigram. It did not say whether those interests would be converted, repurchased, retained, or otherwise treated after the proposed transaction, and it did not report either company’s position on the deal.

Home Phoneline Networking Alliance work
In mid-March 1999, Epigram had agreed with Lucent Microelectronics to work jointly on specifications for the Home Phoneline Networking Alliance. EE Times said the status of that arrangement was uncertain after Broadcom’s announcement. The report provides no basis for saying that Broadcom controlled the alliance, ended the cooperation, or changed the specifications.
Independent reader supportYour contribution helps us test, update, and keep practical guides available for everyone.Risks embedded in the proposal
- Share issuance: issuing 4.6 million shares could dilute existing Broadcom shareholders, although the available report does not quantify the percentage.
- Valuation volatility: the approximately $315 million figure depended on Broadcom’s market price rather than a fixed cash payment.
- Technical adoption: performance would depend on actual telephone-wiring conditions, noise, topology, compatible equipment, and manufacturers’ willingness to include the controllers.
- Commercial maturity: sampling had begun, but the report does not establish volume production or customer shipments.
- Competition: Conexant and AMD were already identified as competing home-networking participants.
- Standards coordination: uncertainty around the Lucent relationship could affect interoperability work.
What the announcement does—and does not—establish
| Question | What the April 1999 report establishes |
|---|---|
| Was an acquisition announced? | Yes. Broadcom announced plans to acquire Epigram on April 25, 1999. |
| What was offered? | 4.6 million Broadcom Class B common shares. |
| What was the reported value? | Approximately $315 million, calculated from Broadcom’s prior Friday closing price. |
| Did the deal definitely close? | Not established by the available contemporaneous report. |
| Did iLine 10 reach volume production? | Not established; the report only says prototypes were demonstrated and devices began sampling in March 1999. |
| What happened to Panasonic, 3Com, or the Lucent agreement? | Their post-announcement treatment and the agreement’s eventual status are not reported. |
Historical significance
The proposal captures a late-1990s attempt to solve the “last few meters” problem inside the home. Broadband access was moving toward the residence, while the industry still needed an economical way to connect multiple devices without rewiring houses. Epigram’s phone-line controllers offered one possible bridge between those two markets, and Broadcom’s interest reflected the appeal of pairing access-network silicon with in-home distribution technology.
Any account that goes beyond that announcement—claiming a completed acquisition, final consideration, commercial iLine 10 shipments, or a later Broadcom home-networking outcome—requires separate closing and product records. The cited EE Times report documents the proposal and its context, not those later results.
