New Product Announcements from Ettus R.

=====================================================

We are very excited to announce the immediate availability of the  
latest low cost Software Radio product from Ettus R., the  
USRP™ B100. The B100 has the following features:

- USB 2.0 interface
- Xilinx Spartan 3A-1400 FPGA
- Compatibility with our entire daughterboard family
- Fully supported by UHD drivers
- Dual 64 MS/s 12-bit ADCs
- Dual 128 MS/s 14-bit DACs
- Onboard TCXO for precise frequency control
- 10 MHz and 1 PPS inputs for external references
- Flexible clocking from 10 MHz to 64 MHz
- 8 MHz of RF bandwidth with 16 bit samples
- 16 MHz of RF bandwidth with 8 bit samples

The price is $650 each, and the B100 is in stock and ready to ship.

=====================================================

The USRP E110 has a larger FPGA (Spartan 3A-DSP 3400) than  
the E100, but is otherwise the same. This is perfect for those who  
wish to offload DSP operations from the main ARM processor.

Both the E100 and E110 are now fully compatible with the GPSDO.

The price of the USRP E110 is $1500 and the E100 is $1300.  
Both the E100 and E110 are in stock and ready to ship.

=====================================================

As always, you can purchase all of our products through:

```

and you can contact removed\_email\_address@domain.invalid if you have any further  
questions.

Thanks,

Hi Matt,

just wondering what the PPM spec is of the onboard TCXO? Will the  
datasheet  
be available soon?

Thanks

Regards  
Richard

2.5 ppm. Datasheet may not be ready for a week or two.

It can accept 10 MHz and PPS from a GPSDO, but it doesn’t have a serial  
port  
for position and time info. You will also need to mount it externally.  
So  
yes, you can use them together, but with some limitations.

The S3A-1400 has twice as many logic cells. An even bigger difference  
is  
that it has 32 hard multiply units, while the cyclone had to use a lot  
of  
general logic resources in order to do multiplies. So the capability is  
more like 3x.

The B100 will have much better clock stability (~2.5ppm over  
temperature)  
even without the GPSDO.
