Analogue and mixed-signal cores join IP library
NewLogic Technologies has expanded its IP library with a range of high-performance analogue and mixed-signal IP cores.
"Our evaluation platform proves the concept of the digital interface and secures the full functionality of our IP in actual silicon as an end to end solution", states Uwe Hering, Sr VP Sales and Marketing at NewLogic.
"We believe this to be a significant milestone that will enable the Wi-Fi market to grow even further, since WLAN can now be considered as a peripheral interface that can easily be integrated into various SoCs or even ASICs".
To meet the demand in the market to integrate WLAN MAC and modem functions into SoCs, NewLogic developed the digital HiSS interface which migrates all analogue functions such as ADC/DAC and PLL out of the modem into the radio.
Having a purely digital MAC/baseband solution supports the migration to smaller geometry technologies independently of mixed signal constraints, to reduce production test time, to improve performance (since the ADC/DACs can benefit from a higher supply voltage on the RF chip) and to offer improved yield.
Another benefit of the HiSS interface is the possibility to move the radio up to 1m away from the modem - this is ideal for laptop applications where the radio can be placed behind the LCD screen, while the modem remains on the motherboard or on a MiniPCI module.
A low-cost ribbon cable can then replace the coax cables that would instead be used to connect the radio on the motherboard to the antennas behind the screen.
The HiSS interface uses five standard LVDS pairs running at 240MHz and one standard digital IO.
The respective I and Q data are multiplexed in serial with control and address data within a digital stream.
As the NewLogic Wild radio transceiver contains the functions to detect the presence of a valid input signal (eg RSSI) without the use of the modem and MAC, the HiSS interface is shut off when no data are transmitted and therefore reduces the overall system power consumption.
As NewLogic's Wild IP, including the radio transceiver, is developed in CMOS technology, the MAC, modem and radio can also be easily integrated onto a single die as a single chip WLAN solution.
NewLogic's Wild IP with its dual-band radio and flexible MAC and modem, is multimode capable offering the 802.11a/b/g features required for today's designs.
It also already supports the latest 802.11e (quality of service), i (security) and h (power control and dynamic frequency selection including radar detection for North America and Europe) extensions essential for implementing state-of-the art Wi-Fi solutions.
All Wild IP blocks are proven in silicon and are available for customers today.
Demonstrations of the silicon implementation and evaluation boards are available on request.
