PRS4000/PRS1025 60 GHz WiGig Chipset Product Brief
General Description The PRS4000 WiGig baseband and PRS1025 WiGig radio are compliant with the single carrier modulation and coding schemes of the IEEE 802.11ad specifications (MSC0 to MSC12). This chipset implements a low cost, low power, high performance SuperSpeed USB 3.0 to WiGig device. The PRS4000 includes a USB 2.0 and 3.0 device/host system interface. Supporting link speeds of up to 2.0 Gb/s, it is possible to configure the PRS4000 as a multi‐gigabit WiGig USB adaptor or as the 60 GHz wireless connection for a WSB peripheral device. The PRS4000 MAC incorporates two powerful RISC processors to provide the highest flexibility in supporting 801.11ad MAC functionality. CPU code boot loading is supported from the USB interface or external serial flash. Security is ensured through the use of AES with a 128‐bit key and a 128‐bit block size utilizing GCM for data confidentiality and GMAC for authentication and integrity. RSNA and 802.1X are used to provide a robust authentication and association procedure. The MAC includes sufficient internal memory to buffer data transfers to and from the PHY as well as receiving/transmitting packets to the host interfaces. No additional RAM is required. The PRS4000 PHY is capable of modulating/demodulating all control and single carrier π/2‐BPSK, π/2‐ QPSK and 16‐QAM WiGig coding schemes (MCS0 to MCS12) up to a maximum rate of 4.62 Gb/s. LDPC forward error correction maximizes performance in unreliable or noisy communication channels. The PRS4000 also includes a highly configurable programmable IO subsystem consisting of GPIO, UART, SPI, TWI, PWM and JTAG. The firmware incorporates multiple layers of debug functionality such logging and extensive statistic and event counters. The PRS4000 supports seamless connection to all Peraso 60 GHz radios: The PRS1025 is a single chip IC incorporating an integrated patch antenna with 8.5 dBi peak gain across the entire 60 GHz band The PRS1125 is a single chip IC with available 60 GHz Tx and Rx antenna ports allowing custom antenna designs The PRS2152 and PRS2153 are highly integrated module solutions with an available WR‐15 waveguide interface allowing simple interface to common 60 GHz waveguide components
