The headline rating is ±1.5ppm frequency stability across the full operating range of -30°C to 85°C, which means the total timing error budget over temperature stays within 1.5 parts per million — critical for any PLL reference or ADC clock where phase noise integrates directly into the signal chain. ## Clock tree integration — supply, current, and the 3V rail Powered from a single 3V rail drawing up to 2mA — the supply current is low enough that a dedicated LDO is often unnecessary if the upstream rail is clean, but a noisy digital rail will couple through the VCTCXO's control voltage sensitivity. The clipped sine wave output presents a lower harmonic content than a CMOS square wave, reducing spurious content in the downstream mixer or PLL — the phase-noise plot does not lie, and a clean output stage means less cleanup work in the loop filter. ## 2.00×1.60mm footprint — what the 4-SMD no-lead package means on the board The 2.00 mm × 1.60 mm body with 0.80 mm seated height is the standard compact oscillator footprint — the no-lead (DFN-style) terminations sit flush to the PCB, so the land pattern must be accurate or the coplanarity error shifts the resonance. Solder paste volume and reflow profile matter more than usual: undersized pads increase standoff tilt; oversized pads can shift the effective capacitance loading the crystal resonator and detune the trim range. The 3V supply decoupling should be as close to the device as the layout allows — typically 100 nF plus optional 10 nF for the HF content.","metaTitle":"ASVTX-13-A-38.400MHZ-D15-T VCTCXO, ±1.5ppm, 38.4MHz","metaDescription":"Abracon ASVTX-13 VCTCXO, 38.4 MHz clipped sine wave, ±1.5ppm stability, 3V, -30°C~85°C, 2.00×1.60mm 4-SMD.

A standard XO or CMOS oscillator at this frequency typically specs ±50ppm or worse, so the VCTCXO is chosen when the timing budget cannot tolerate that drift — in PLL references, frequency synthesizers, and precision ADC or DAC clocking."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/abracon-llc/ASVTX-13-A-38.400MHZ-D15-T","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/abracon-llc/ASVTX-13-A-38.400MHZ-D15-T when reusing this data.
