Product details
Overview
552CJ000316DG from Skyworks Solutions is a dual-frequency voltage-controlled crystal oscillator (VCXO) delivering two factory-programmed output frequencies in the 10–945 MHz range, with CMOS output, 1.8 V supply, ±20 ppm temperature stability, and 33 ppm/V tuning slope. It serves as a low-jitter timing source in optical modules and clock/data recovery circuits where dual-rate flexibility and high reliability are required.
For engineers reviewing the 552CJ000316DG datasheet, 552CJ000316DG pinout, 552CJ000316DG application, or 552CJ000316DG equivalent, this page provides verified technical context, package-validated pin functions, real-world jitter performance (0.63 ps RMS phase jitter at 125–500 MHz), and direct alternative options for dual-frequency VCXO selection in telecom and datacom systems.
Technical Context
The 552CJ000316DG implements Skyworks' third-generation DSPLL® architecture to synthesize two discrete output frequencies from a single internal fixed-crystal reference, eliminating need for multiple crystals. Its 1.8 V CMOS output supports up to 160 MHz and delivers 45–55% duty cycle symmetry with <1 ns rise/fall time.
Frequency selection is controlled via the FS pin (with internal 17 kΩ pull-up to VDD), enabling instantaneous switching between the two programmed frequencies. Tuning is analog via the VC pin, supporting ±12 to ±375 ppm absolute pull range depending on KV selection - here configured for 33 ppm/V to minimize noise coupling while meeting APR requirements.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Nominal Frequency | Two factory-set frequencies in 10–945 MHz band; CMOS output limited to ≤160 MHz |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-frequency VCXO applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Si552DJ000316DG | Same package and pinout; LVDS output instead of CMOS; 2.5 V supply; 33 ppm/V KV | Requires differential termination (100 Ω); suited for FPGA transceivers with LVDS clock inputs | Select when interfacing with high-speed SerDes requiring differential signaling and tighter skew control. |
| Si552AF000108DGR | Same family; 3.3 V LVPECL output; 135 ppm/V KV; ±50 ppm stability; tape-and-reel packaging | Higher power (120 mA), higher jitter (0.50 ps), wider APR - optimized for wide-loop PLLs in RF systems | Choose for applications needing larger tuning range and compatibility with legacy LVPECL infrastructure. |
Compared with 552CJ000316DG, Si552DJ000316DG offers lower noise floor in differential mode but requires board-level termination, while Si552AF000108DGR trades higher jitter and power for greater APR and legacy interface compatibility - making 552CJ000316DG optimal for low-power, single-ended, precision-tuned telecom timing.

FAQ
What is the nominal output frequency configuration of the 552CJ000316DG?
The 552CJ000316DG is factory-programmed with two specific output frequencies within the 10–945 MHz range, encoded in its six-digit frequency designator "000316". As a CMOS-output device, both frequencies are ≤160 MHz. The exact values are defined at order time using Skyworks' online configuration tool and shipped pre-programmed - no field reconfiguration is supported.
Does the 552CJ000316DG support tristate functionality?
No, the 552CJ000316DG does not include an output enable (OE) function or tristate capability. Its CMOS output is always active when powered within specified operating conditions. For applications requiring clock gating, external logic or a dedicated clock buffer with OE must be used in conjunction with the 552CJ000316DG.
What is the maximum allowable control voltage range on the VC pin of the 552CJ000316DG?
The VC pin of the 552CJ000316DG accepts a control voltage from 0 V to VDD (1.8 V), per Absolute Maximum Ratings. Operation across the full 0–1.8 V range enables the full ±12 ppm minimum absolute pull range. Exceeding VDD or going below 0 V risks permanent damage, as specified in Table 10 of the datasheet.
How does the FS pin behavior affect frequency switching timing in the 552CJ000316DG?
The FS pin of the 552CJ000316DG triggers instantaneous frequency switching with a maximum settling time of 10 ms after assertion, as specified in Table 3. Its internal 17 kΩ pull-up to VDD ensures default selection of the first frequency (FS = 0) during power-up or floating states, simplifying system initialization without external biasing.
Is the 552CJ000316DG compliant with lead-free and RoHS requirements?
Yes, the 552CJ000316DG is Pb-free and RoHS-compliant, as confirmed in Section 6.2 of the datasheet and Table 8 (Environmental Compliance). The top marking includes a "+" symbol to indicate RoHS compliance, and it meets JEDEC J-STD-020C MSL 1 handling requirements for moisture sensitivity.
