The Pulse~LINK PL3100 family consists of four integrated circuits, enabling CWave communication technology over various physical media. At the core of the family are the PL3120 UWB transceiver and the PL3130 baseband components. The philosophy of the system is to allow as much adaptation in the protocol and the signal as possible, to match the application and environment. Therefore, the PL3120 is highly configurable and thus depends heavily on the PL3130 baseband component for configuration, adaption, optimization and performance tuning. The PL3130’s functionality also encompasses the Media Access Control layer that supports the 802.15.3 standard, and provides robust and proven networking and communication capability.
Due to the ultra-low power used when UWB is transmitted over the air, no “power amplifier” is necessary. The output of the PL3120 is sufficient. In all cases, an additional Low Noise Amplifier (LNA) on the receive input is useful, especially in light of the wide dynamic range capability of the Pulse~LINK UWB implementation.
Thus, to compliment the PL3120 and PL3130, the PL3110 and PL3111 are available. Both have the requisite LNA, and the PL3111 has an additional power amplifier for use over wired media, where higher power output can be utilized to further enhance speed and range.
PL3120 Ultra-Wideband Transceiver
The PL3120 Ultra-Wideband Transceiver RFIC is an integral part of Pulse~LINK’s CWave™ chipset solution for high-speed wireless or connectivity over coaxial cable. The transmitter block serializes data from the PL3130 baseband+MAC chip, generates the carrier and modulates with high-speed data. The PL3120 directly interfaces with the PL3130 baseband+MAC and is preconfigured, together with the PL3130, in a single package. For wireless operation, the PL3110 Low Noise Amplifier (LNA) is required. For operation over coax, the PL3111 Analog Front End (AFE) is required.
PL3130 Ultra-Wideband Baseband & MAC (BBM)
The PL3130 Ultra-Wideband Baseband+MAC chip comprises a Media Access Controller (MAC) and a Baseband Physical Layer (BB PHY) encoder/decoder. The basic PL3130 communication and control is performed via a standard 32-bit PCI Bus over which instructions, status, and transport data are transferred. The MAC core consists of an embedded 802.15.3b MAC Protocol Processor (MPP), a TDMA Hardware Controller (THC), a 32-bit PCI Bridge Controller (PBC), DDR memory Controller (DRC), a Serial FLASH memory Controller (SFC), and the transport signal and control interfaces for the PL3120 Transceiver RFIC and PL3110 LNA/PL3111 AFE. The PL3130 is preconfigured, together with the PL3120, in a single package. For wireless operation, the PL3110 Low Noise Amplifier (LNA) is required. For operation over coax, the PL3111 Analog Front End (AFE) is required.
PL3110 Ultra-Wideband Low Noise Amplifier
The PL3110 UWB LNA chip consists of a two-LNA-block low-noise wideband amplifier designed to connect to a UWB antenna system. The LNA amplifies an RF receive channel, operating over a wide frequency range from 3.3 – 4.8 GHz optimized at the center frequency of 4 GHz. The PL3110 LNA provides a single-channel receive signal source to the PL3120 Transceiver RFIC.
PL3111 Coax Analog Front End
The PL3111 AFE chip consists of a two-LNA-block low-noise wideband amplifier designed to connect to a coax cable interface. The LNA amplifies an RF receive channel, operating over a wide frequency range from 3.3 – 4.8 GHz optimized at the center frequency of 4 GHz. The PL3111 AFE provides a single-channel receive signal source to the PL3120 Transceiver RFIC.
