Fellows,
You may take a look here https://www.olimex.com/dev/tms320-jtag.html
It is a cheap LPT Wigler-like emulator for TMS320C28xx series.
A unit of this type is already two months in use here with CCS3.3. It is OK.

karote,
Take a look near to the carrier of your's VCXO PLL output. You may have low frequency perturbations
or small jumps in the order of 10 - 20Hz.
It may happen very easy - because of the small VCXO gain the loop may become a litle bit instable,
especilally if the division ratio is low (...
pll chip normalized phase noise
Amicloud,
It will be not so "pretty stight forward" as yendori said. Minus 90dBc/Hz at 1kHz will be not an easy task on 2GHz. You will need a low noise PLL chip and good low noise VCO. Something like LMX2347 (integer PLL with -217dBc normalized phase detector...
Re: P1dB and IP3 mixer
Hi,
Typical requirements of ETS300-086 Standard for a VHF or UHF mobile radio's receiver:
(1) sensitivity of -113dBm (0dBuV EMF) at 10dB S/N;
(2) Third order Intermodulation Distortion of -70dB min ( with 2 interfering signals detuned +25kHz and +50kHz (and/or -25...

Hi Pit,
Search for HP8502A manual in hp folder of bama.sbc.edu website.
Search Elektroda too - long time ago somebody was uploaded here very nice inside photos of HP8502A. The name of topic was "ultra wideband directional coupler" or something similar.

fsk caller id protocol
Hi,
take a look at Texas Instruments Web Site. Search for slaa037 Application note.
There is a good example of FSK demodulator. It is writen for MSP430, but it
will help you, I hope.
Best Regards,

bootloader msp430
Hi,
It is a flash programmer. It's working fine.
You can use it with TI Flash Emulation Tool.
Read the files on that website:))

Hi,
In the first case , using a resistor between the base and ground is nessesary
if:
- the control signal does not go to ground ;
- if the signal circuit can go in hi-impedance state,
for example, if it is delivered from a uP during reset.
The second case is different, RX resistor may...
xds510 clone
Hi eltonjonh,
I think, you miss XDS510 control register in your hardware. It is separate from
ACT8990. Take a look on ES10 files at: h**p://www.agelectronics.co.uk/download.html for register description.
Best regards,
Stoyanov
