Schoffer: There was a basher who posted on the RB board (I don't remember his/her handle)who never could understand the correct use and spelling of the word "lose" and mistakenly used the term "loose".

See the first sentence of your post 3827.

Hey, everybody, looks like another one is nailed!!!!

Schoffer, you don't know me, but I used to post here and read the mail on RB all of the time but never even signed up to post there, for obvious reasons. AND, I haven't posted HERE since you came on board.

I'm no fan of SEVU at the moment, since it cost me a bundle, but to you I can only say: GET LOST!!!

First of all what I search for either walks, flys or floats.

Secondly I have both data sheets in my hand and they look very cloes to the same but I am not an electronics expert. But the MC12149 even says it's tuning voltage is 20mhz.

As far as I can see the chip is not the problem as you describe.

Schoffer, you've lost the argument.

Stop lying to us.

20 MHz Oscillator....Found ONE!! I think

Not sure how old this is, but I found an alternative to the Motorola MC12148...here is a copy of the page I found, I haven't called the company.

SaRonix Introduces Miniature

Surface Mount Voltage Controlled Crystal Oscillator



Menlo Park, California -- SaRonix, a worldwide manufacturer of electronic components, is releasing its latest ST1307/1507 and ST1317 /1517 series Voltage Controlled Crystal Oscillators (VCXOs). Measuring in at just 5 x 7 x 1.8mm these ceramic packaged surface mount oscillators are available over a wide range of frequencies and specifications.

Their low profile and small footprint makes these new oscillators ideal for use in the high-density circuit designs dictated by the ongoing miniaturization of portable electronic equipment used in PCMIA cards, palmtop computers, cell phones and LAN/WAN data communication adapters, etc.

“The biggest challenge in designing the Series was to maintain the same functionality and performance, but in a package with a much smaller volume.” explains SaRonix’s Beat Kocher. “These oscillators are perfect for use in telecom, wireless, and phase-locked loop applications where space conservation, low power consumption, and high-performance are a priority.”

The two series provide a rugged, stable reference source for frequencies ranging from 1 to 31.999 MHz for the S1307/1507 and 32 to 125 MHz for the ST1317/1517 Series. Rated stability is ±50 ppm over all conditions including shock, vibration, and changes in supply voltage, load, and operating temperatures.

SaRonix designed the ST1307/1507 Series with an eye toward keeping noise as low as possible. Phase noise readings of -95dBc/Hz at 100 Hz; -110dBc/Hz at 1 kHz; and -100dBc/Hz at 10 kHz are exceptional for oscillators of this small size and low cost.

The output is compatible with current HCMOS and TTL logic families, and comes equipped with an industry standard Tri-State output feature.

The recommended supply voltages are 3.3V ±10% and 5V ±5% with supply currents ranging from 15 to 65mA max, depending on frequency range.

Designed to conform to most automated assembly environments, these leadless, ceramic, surface mount oscillators are equipped with six gold plated contact pads and shipped in 16mm tape with 500 pieces per reel.

SaRonix is an ISO9001/ISO9002 certified manufacturer that supports its worldwide customer base with engineering, sales and manufacturing facilities in the US, Europe and Asia. For more information please call SaRonix at phone [phone] or fax [phone].
