Convertor offers 1.2GHz analogue input
bandwidth
A 12bit 250Msample/s high IF sampling analogue to digital convertor offers a 1.2GHz analogue input bandwidth along with the lowest power consumption in its class.
Linear Technology has announced the LTC2242-12, a 12bit 250Msample/s high IF sampling analogue to digital convertor (ADC) that offers a 1.2GHz analogue input bandwidth along with the lowest power consumption in its class Operating on a 2.5V supply, the LTC2242-12 consumes just 740mW, even lower than its nearest competitor, operating on a 1.8V analogue supply

Card power chip meets smart and SIM standards
The LTC4557 is a dual SIM/smart-card power supply and level translator, which provides both 1.8 and 3V SIM power and digital signal level shifting from a 3 x 3mm QFN package.
RF mixers take transformers onboard
Linear Technology has released two new high linearity up-converting RF active mixers with integrated RF transformers.
Along with improved power efficiency, the low power dissipation reduces time and costs spent on thermal design considerations and helps improve long term product reliability.
The LTC2242-12 can be driven with an analogue input range of 2V peak-peak to enable excellent SNR performance of 65.1dB at 240MHz input frequency, with SFDR of 74dB.
The LTC2242-12 is part of a pin-compatible family of 10 and 12bit ADCs, sampling at 170, 210 and 250Msample/s.
It is pin-compatible with the existing 3.3V LTC2220 family, offering an upgrade path to higher sampling rates with considerably lower power dissipation.
These parts provide the flexibility to select between LVDS, full-rate CMOS or demultiplexed CMOS outputs for easy interface to DDCs.
The digital output supply can be powered from 0.5-2.6V, allowing direct connection to low voltage digital interfaces.
The LTC2242-12 low power family is available in a small 9 x 9mm QFN package, and includes integrated bypass capacitance that further reduces the overall solution size.
The LTC2242-12 family is supported with LVDS demo boards for quick device evaluation and can be purchased online.
Samples and demo boards for the LTC2242-12 family are available today.
Available in both commercial and industrial temperature grades, they are competitively priced at $59 each in 1000-piece quantities. Request a free brochure from Linear Technology Corp ...
