It operates from a 3.3 V supply, achieves <1.1 ps RMS phase jitter (12 kHz–20 MHz), and supports telecom clocking, low-jitter PLLs, and FPGA/ASIC timing applications.

For engineers reviewing the 515GAA32M7680CAGR datasheet, 515GAA32M7680CAGR pinout, 515GAA32M7680CAGR application, or 515GAA32M7680CAGR equivalent, this page provides verified specifications, package layout, real-world use cases, and validated alternative options for stable, low-phase-noise frequency control in space-constrained designs.

Technical Context

The 515GAA32M7680CAGR implements Skyworks' proprietary PLL-based synthesis architecture using a fixed AT-cut fundamental-mode crystal, enabling precise 32.768 MHz generation without custom crystals. Its integrated control loop delivers 1% control voltage linearity and >10 kHz modulation bandwidth.

This VCXO features factory-programmed configuration including output enable polarity (active-low), 3.3 V supply, CMOS single-ended output, and ±120 ppm/V Kv slope - eliminating NRE and long lead times. It achieves high power supply noise rejection (≤3.5 ps additive jitter at 1–500 kHz) and meets MIL-STD-883 environmental reliability standards.

FAQ

What is the nominal output frequency and stability of the 515GAA32M7680CAGR?

The 515GAA32M7680CAGR is factory-programmed for a nominal output frequency of 32.768 MHz with ±20 ppm temperature stability across –40 °C to +85 °C. This specification is guaranteed per Skyworks' datasheet Table 3 and applies directly to the 515GAA32M7680CAGR configuration, making it suitable for precision RTC and timing reference applications where long-term accuracy is critical.

Does the 515GAA32M7680CAGR support active-high or active-low output enable?

The 515GAA32M7680CAGR uses an active-low output enable (OE) pin, as indicated by the "A" in the third option code of its part number. When OE is driven low, the CLK output enters high-impedance state; when pulled high (via internal pull-up), the oscillator operates normally. This behavior is confirmed in Table 12 of the Skyworks datasheet and applies specifically to the 515GAA32M7680CAGR variant.

What is the control voltage range and tuning slope for the 515GAA32M7680CAGR?

The 515GAA32M7680CAGR accepts a control voltage (Vc) from 0.33 V to 2.97 V (0.1× to 0.9×VDD) and has a factory-set tuning slope (Kv) of ±120 ppm/V, as specified in the second option code "A". This enables predictable frequency deviation of ±1.56 ppm per 13.2 mV change - critical for closed-loop synchronization in telecom and networking equipment using the 515GAA32M7680CAGR.

Can the 515GAA32M7680CAGR be used with a 2.5 V supply?

No - the 515GAA32M7680CAGR is configured for 3.3 V operation, as indicated by the first option code "G" in its part number. It is not rated for 2.5 V supply; attempting to operate it at 2.5 V may result in failure to start, degraded jitter performance, or undefined output levels. The 515GAA32M7680CAGR requires 2.97–3.63 V per Table 1 of the Skyworks datasheet.

What package type and dimensions does the 515GAA32M7680CAGR use?

The 515GAA32M7680CAGR uses a 2.5 × 3.2 mm, 6-pin surface-mount package (CLCC-style) with gold-over-nickel contact pads. Its outline conforms to Skyworks' specification in Figure 7 and Table 18, with nominal body dimensions of 2.5 mm × 3.2 mm × 0.55 mm height. This compact footprint is optimized for high-density PCB layouts in telecom and portable industrial devices using the 515GAA32M7680CAGR.
