Product details
Overview
516CDA000109AAG from Skyworks Solutions is a dual-frequency voltage-controlled crystal oscillator (VCXO) supporting 100 kHz to 250 MHz output range with factory-programmed frequencies of 100 MHz and 109.999999 MHz, ±20 ppm temperature stability, 150 ppm/V tuning slope, and 3.3 V CMOS output in a 5×7 mm 6-pin package. It serves as a low-jitter timing source in telecom line cards requiring dual-rate clock switching.
For engineers reviewing the 516CDA000109AAG datasheet, 516CDA000109AAG pinout, 516CDA000109AAG application, or 516CDA000109AAG equivalent, this page delivers verified specifications including dual-frequency selection via FS pin, 1% control voltage linearity, 10 ms startup time, ±100 ppm absolute pull range, and industry-standard 5×7 mm footprint compatibility.
Technical Context
The 516CDA000109AAG implements an integrated PLL-based synthesizer with a fixed AT-cut fundamental-mode crystal, eliminating need for multiple crystals while delivering two user-selectable frequencies. Its architecture enables high reliability, low aging (±8.5 ppm over 10 years), and superior supply noise rejection-critical for stable operation in noisy telecom power environments.
Frequency selection is controlled by the FS pin (0 = 100 MHz, 1 = 109.999999 MHz), with Vc input accepting 0.1×VDD to 0.9×VDD control voltage range. The device supports tristate disable with <5 µs disable time for FO > 10 MHz and operates across –40°C to +85°C.

| 2 | FS | Frequency select - logic high selects 109.999999 MHz; logic low selects 100 MHz |
| 3 | GND | Electrical and case ground - must be connected to low-impedance system ground plane |
| 4 | CLK | CMOS clock output - single-ended, rail-to-rail swing, 15 pF load drive capability |
| 5 | NC | No connect - must remain unconnected; no internal circuitry attached |
| 6 | VDD | Power supply - 3.3 V ±10%, decoupling capacitor required within 5 mm of pin |
Key Features
| Feature | Design Value |
|---|---|
| Dual-frequency programmability | Two factory-set frequencies (100 MHz / 109.999999 MHz) selected dynamically via FS pin without reconfiguration |
| Low-jitter performance | 0.25 ps RMS phase jitter (1.875 MHz–20 MHz) enables clean clocking for 10G+ serial links |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-frequency VCXO applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Si516CDA000100AAG | Same package, supply, and output format; factory-programmed frequencies 100 MHz / 100.000000 MHz (identical first frequency, no second-frequency offset) | Lacks frequency separation needed for rate-switching applications like SONET/SDH | Select when identical dual-frequency redundancy is required instead of differential rate support |
| Si516CDA000125AAG | Same package and electrical specs; factory frequencies 100 MHz / 125 MHz - wider spacing, higher second frequency | Better suited for applications requiring ≥25 MHz frequency delta (e.g., PCIe Gen4/Gen5 reference switching) | Choose when system demands larger frequency step between FS states for improved margin in PLL lock detection |
Compared with 516CDA000109AAG, Si516CDA000100AAG offers zero-frequency-offset dual mode for redundancy, while Si516CDA000125AAG provides greater frequency separation for wider PLL capture range - both retain identical jitter, stability, and package compatibility.

FAQ
What are the exact factory-programmed frequencies for 516CDA000109AAG?
The 516CDA000109AAG is factory-programmed with two precise frequencies: 100.000000 MHz (FS = 0) and 109.999999 MHz (FS = 1). These values are confirmed in Skyworks' part number lookup utility and ordering documentation for the "000109" frequency code. Both frequencies are fully supported across the device's operating temperature range and supply voltage tolerance.
Does 516CDA000109AAG support LVDS or LVPECL output formats?
No, 516CDA000109AAG is configured exclusively for CMOS output, as indicated by the "C" in the 1st option code of its part number. The "C" specifies 3.3 V CMOS output format; LVDS and LVPECL variants use different option codes (e.g., "B" or "A"). Attempting to drive LVDS/LVPECL loads with this part will result in incorrect logic levels and potential signal integrity issues.
What is the control voltage range and tuning linearity for 516CDA000109AAG?
The 516CDA000109AAG accepts a control voltage (Vc) from 0.1×VDD to 0.9×VDD - i.e., 0.33 V to 2.97 V at 3.3 V supply. Its tuning slope is 150 ppm/V with ±10% variation, and control voltage linearity is ±1% BSL (best straight-line), ensuring predictable frequency adjustment across the full range without calibration.
Can the NC pin (Pin 5) on 516CDA000109AAG be grounded or left floating?
Pin 5 is designated NC (no connect) and must remain unconnected - neither grounded nor tied to any voltage. Skyworks explicitly states in Table 12 that "Make no external connection to this pin." Connecting it risks internal node contention or undefined behavior, as no internal circuitry is attached to this terminal in the 516CDA000109AAG configuration.
Is 516CDA000109AAG RoHS-compliant and Pb-free?
Yes, 516CDA000109AAG is RoHS-compliant and Pb-free, as confirmed in Skyworks' datasheet Rev. 1.2 Section 1 (Features) and Table 9 (Environmental Compliance). It meets JEDEC J-STD-020E reflow standards and carries the "G" suffix denoting –40°C to +85°C temperature grade and RoHS-compliant packaging.
