Semtech Announces A New PHY IP Platform From Its Snowbush IP Group That Supports JESD204B, CPRI And OBSAI

Semtech Corporation (Nasdaq: SMTC), a leading supplier of analog and mixed-signal semiconductors, today announced the availability of a multi-standard silicon IP (SiIP) PHY that supports the latest new standards for high-speed wireline and wireless networks. The new SBMULTR2T2812G SiIP PHY is silicon-proven and was developed by Semtech’s Snowbush IP Group, which is focused on designing high-speed serial interface IP.

The new platform supports JESD204B (JEDEC Standard), Common Public Radio Interface (CPRI™) and open base station architectural initiative (OBSAI). The IP also supports 10GBase-KR, CEI-11G and PCI-Express 3.0.

The SBMULTR2T2812G SiIP PHY is tuned to meet the performance of each standard through a programmable profile that sets a set of registers that control the operation of the PHY. The programmable register set controls key electrical operations and allows for post-silicon corrections to adjust to different operating environments. The PHY is available today in dual- and quad-lane versions. The platform supports advanced channel equalization and adaptation circuitry to optimize performance while using minimal power at each data rate and in the smallest silicon area.

The new PHY is currently being used by Texas Instruments in its base station devices. “Our team is using the Semtech-Snowbush IP PHY to support the serial standards in our KeyStone-based base station SoCs,” said Sanjive Agarwala, TI Fellow & Director of Worldwide Silicon Development for TI’s Processor business. “Semtech’s IP architecture is quite adaptable to our requirements and the effective integration support and project execution Semtech provided enabled us to quickly integrate their PHY into our SoCs, helping speed development time.”

The Semtech-Snowbush SBMULTR2T2812G SiIP PHY supports the three major enhancements in JESDB, a 12.5Gbps data rate, deterministic latency and harmonic clocking. These features differentiate JESDB from JESDA. The physical interface specification is compliant with the OIF Common Electrical Interface (CEI) 6G-SR at 6.25Gbps and CEI-11G-SR at 12.5Gbps.
