I like to have a start frequency, to get this resistor R2 need to be placed and a signal with a frequency depending on the R2 value will appear without any input signal. When a input signal on pin 14 is applied with a higher frequency then adjusted, heavy jitter will appear What can I do to have a start frequency with locking for higher frequencies without the jitter?CD74HC4046Ahttps://e2e.ti.com/support/logic-group/logic/f/logic-forum/1663534/sn74lvc1g332-sn74lvc1g332dckr-rjc/6451519Fri, 14 Aug 2026 20:23:00 GMTcb01d8b2-d089-468d-babb-77d1d8683490:35785c7b-5815-4f35-8440-4b6d61ae50aaNikki DengelHi, See the following results for SN74LVC1G332DCKR : Result- Theta JA-High K (standard datasheet value) 245.4 Result-Theta JC, top (standard datasheet value) 150.5 Result-Theta JB (standard datasheet value) 139.1 Result- Psi JT (standard datasheet value) 65.6 Result- Psi JB (standard datasheet value) 138.8 Result-Theta JC, bottom (standard datasheet value) n/a Regards, Nikkihttps://e2e.ti.com/support/logic-group/logic/f/logic-forum/1673434/sn74hc4020-rthetajc-for-sn74hc4020/6451494Fri, 14 Aug 2026 19:44:00 GMTcb01d8b2-d089-468d-babb-77d1d8683490:ca2e8de4-e4d4-4286-a23f-1973f0bff3f4Nikki DengelHi Avery, I'll submit a request for it.

Yes, can I still get the RthetaJC value?https://e2e.ti.com/support/logic-group/logic/f/logic-forum/1673434/sn74hc4020-rthetajc-for-sn74hc4020/6451439Fri, 14 Aug 2026 18:36:00 GMTcb01d8b2-d089-468d-babb-77d1d8683490:f57a275d-cd29-4a2b-87f3-1f06ab2f1badNikki DengelHi Avery, SN74HC4020NSR is not recommended for new design because there are plans for its end of life. Do you still want the RthetaJC? I can try to find it, but I recommend looking at the other package options for this device.https://e2e.ti.com/support/logic-group/logic/f/logic-forum/1673391/sn74lvc1gx04-sn74lvc1gx04-unable-to-oscillate-with-custom-saw-resonators/6451399Fri, 14 Aug 2026 17:57:00 GMTcb01d8b2-d089-468d-babb-77d1d8683490:f6f06ef7-457b-45d3-8589-9c632636a199Amir JahanfarThank you for your reply. It seems that the gain is the main issue, as you mentioned. I do have an alternative discrete circuit, but I was hoping to use the SN74LVC1GX04 because of its simple configuration and low component count. Thankshttps://e2e.ti.com/support/logic-group/logic/f/logic-forum/1673391/sn74lvc1gx04-sn74lvc1gx04-unable-to-oscillate-with-custom-saw-resonators/6451392Fri, 14 Aug 2026 17:47:00 GMTcb01d8b2-d089-468d-babb-77d1d8683490:be614ee4-2208-4532-89f7-cfe21c1970abAmir JahanfarThis is the typical schematic that I used with 3.3Vcc. Also, I increased the Vcc up to 5.5V but still I could not get any oscillation.https://e2e.ti.com/support/logic-group/logic/f/logic-forum/1673391/sn74lvc1gx04-sn74lvc1gx04-unable-to-oscillate-with-custom-saw-resonators/6451360Fri, 14 Aug 2026 17:10:00 GMTcb01d8b2-d089-468d-babb-77d1d8683490:3835f6ae-6ffc-4557-8ac4-31c56f8299a8Emrys MaierHey Amir, I understand you're setting this up as a Pierce oscillator similar to a crystal oscillator. One critical aspect of Pierce oscillators is the required gain -- you need a loop gain of at least 1 (0dB) to maintain oscillation, and the LVC family unbuffered inverters only have about 15dB max at 60MHz (per figure 1 in the datasheet). Your SAW oscillator introduces about 18dB of loss, putting the loop gain at -3dB in the best case, which puts the circuit below the oscillation threshold. The maximum gain of unbuffered inverters like the SN74LVC1GX04 is pretty standardized to about 20dB, so you likely won't find something with much more gain in that category of parts. The bandwidth is caused by the single pole of the load capacitance -- reducing the total load capacitance can increase that bandwidth a bit, but I'm not sure it will be enough for your case. I have not built a SAW-based oscillator circuit, but my understanding is that they are typically built with discrete transistors over ICs. Using a discrete circuit will give you much more control over the loop gain.https://e2e.ti.com/support/logic-group/logic/f/logic-forum/1673434/sn74hc4020-rthetajc-for-sn74hc4020Fri, 14 Aug 2026 16:56:00 GMTcb01d8b2-d089-468d-babb-77d1d8683490:1fe720cc-79c5-4e74-80f2-f6215f4832f9Avery BrillantesPart Number: SN74HC4020 Good Morning, May I have the parameter of RthetaJC for SN74HC4020NSR?

What kind of issue are you experiencing in your production line? You will need to reach out to your local TI sales and applications representative directly to find out if it is possible to order from a specific fab site. If you don't know who your local representative is, you can reach out to TI Support to get in touch with them.

If you have been shipped the wrong part, I recommend reaching out to the customer support center.https://e2e.ti.com/support/logic-group/logic/f/logic-forum/1673391/sn74lvc1gx04-sn74lvc1gx04-unable-to-oscillate-with-custom-saw-resonators/6451294Fri, 14 Aug 2026 16:21:00 GMTcb01d8b2-d089-468d-babb-77d1d8683490:27512224-73c7-402a-a728-0008f8a885ecNikki DengelHi Amir, This device was designed for crystal oscillator circuits in mind, so we don't have any recommendations specific to SAW. That said, I can try to help troubleshoot. What VCC are you using for SN74LVC1GX04? This device will not be able to support high frequencies if the VCC is too low. At VCC = 3.3 or 5 V, you may have better success. Could you provide a schematic? I'll see if I can spot any obvious issues.

You'll notice that the characteristics and specifications in the datasheet are always listed "over recommended operating free-air temperature range (unless otherwise noted)". We do not guarantee device behavior or long-term reliability outside of the Recommended Operating Conditions. You're correct that the most important spec is the Junction Temperature because exceeding that temperature is when damage starts to occur. To answer your question: I wouldn't worry about exceeding the recommended ambient temperature for short periods of time if the maximum junction temperature is observed. I would expect everything to operate normally. That said, you should be aware that I can't make any guarantees when the recommended operating conditions are observed. Regards, Nikki
