u-blox, the Swiss positioning and wireless chip and module
company, announces the immediate availability of the
UBX-G6010-ST-TM, a precision timing single-chip based on GPS
technology with extreme acquisition sensitivity. It is designed for
high-volume applications requiring low-cost precision timing with
accuracy down to 15 nanoseconds such as femtocell basestations
delivering 4G LTE (Long-Term Evolution), CDMA and WiMAX
services.
Femtocell technology is attractive to telecom service providers
as it allows them to deliver mobile communications services via the
Internet, for example ADSL or cable. The service is then
distributed wirelessly to users in localized areas such as home or
office via small femtocell basestations.
This approach lowers the cost of serving consumers by
eliminating the requirement for large, expensive cellular
basestations. The technology also extends mobile phone
coverage to remote or weak signal strength areas while improving
battery life and voice quality. It also eliminates the requirement
for redundant cordless phones and additional telephone number in
the home or office.
Available in a miniature 8 x 8 mm MicroLeadFrame (MLF) package,
the chip delivers two precision time pulse outputs at up to 10 MHz
frequency, plus complete GPS satellite raw data. The chip is able
to operate with only one GPS satellite visible ("single-satellite
tracking"). The unbelievable timing accuracy of 15
nanoseconds is achieved using the built-in quantization error
compensation. Additionally, an integrated time mark and counter
unit can provide precise time measurement of external events.
The chip is qualified according to AEC-Q100, and is manufactured
at ISO/TS 16949 certified facilities. It is guaranteed to operate
from -40°C to 85°C.
