Hi,
Good Day.
I had an RFA 10680 come my way to look for a FFF Form Fit Functional replacement for MCKT, FREQ.TRANSLATOR,LOW JITTER, 31.25MHZ,CMOS OUTPUT,3.3V
The DMS part link below
Crystal Based Frequency Translator FX-500 | Vectron International <- I believe this was the EOL chip we used
Basically, we were using the Vectron FX-500 Frequency Translator in a currently supported circuit card of ours.
From what I can tell key parameters the frequency translator successor needs to match are:
- Needs to operate off a 3.3 VDC supply.
- Needs to be able to drive 3 downstream devices sufficiently, i.e. amplitude, slew rate, and frequency.
- The replacement RF chip needs to have a similar maximum skew/jitter performance for output signals.
- The LOCK output mechanism behaves the same way.
As far as 4 above:
- Capable of locking to an 8 kHz pulse/ BITS clock; Lock Detect
Other important features the FFF replacement must have:
Tri-State Output allows board test
J-Lead Ceramic Package
Additional important characteristics of the replacement Frequency Translator we are looking for:
14mm x 9mm x 4.5 mm 6 J Lead Ceramic Package
Operating temperature -40 to +85°C
Supply Voltage of 3.3V
Operating Frequency of 31.25MHz
Please advise. Thank you very much.
Best Regards,
Ray Vincent
