Skyworks Solutions Inc. 567BAA002604ACG

Overview

567BAA002604ACG from Skyworks Solutions is a factory-programmed, quad-frequency voltage-controlled crystal oscillator (VCXO) based on 4th-generation DSPLL® technology. It delivers four user-selectable frequencies from 0.2 to 3000 MHz with <1 ppb resolution, 100 fs RMS phase jitter (12 kHz–20 MHz), ±20 ppm temperature stability, and operates from 1.8/2.5/3.3 V supply. It serves as a low-jitter clock source in high-speed serial interfaces such as 100G Ethernet and coherent optics.

For engineers reviewing the 567BAA002604ACG datasheet, 567BAA002604ACG pinout, 567BAA002604ACG application, or 567BAA002604ACG equivalent, key selection criteria include VCXO tuning slope (Kv = 60 ppm/V), 5×7 mm CLCC package, LVPECL output compatibility, and PSNR of –83 dBc under 50 mVpp supply ripple - all critical for noise-sensitive PLL and FPGA clocking designs.

Technical Context

The 567BAA002604ACG integrates a fractional-N DSPLL with on-chip power supply filtering and digital loop control, enabling ultra-low jitter across integer and fractional output frequencies without external crystal swaps. Its architecture includes a fixed-frequency crystal oscillator feeding a digitally controlled oscillator (DCO), with ADC-based VC input conditioning and built-in NVM for factory configuration.

It supports pin-controlled frequency selection via FS[1:0] inputs and output enable (OE) with internal 50 kΩ pull-up/pull-down, while maintaining independent voltage control (VC) with 0.1×VDD to 0.9×VDD range and ±10% Kv variation. The device uses a single crystal and programmable DCO to generate up to four distinct frequencies, eliminating custom crystal procurement per frequency.

FAQ

What output format does the 567BAA002604ACG use?

The 567BAA002604ACG is configured as an LVPECL-output VCXO, as indicated by ordering code 'A' in position 5 of the part number. It delivers differential outputs (CLK+, CLK−) with typical swing of 1.1–1.9 VPP depending on frequency, compatible with standard LVPECL receivers and requiring 50 Ω termination to VDD − 2.0 V.

Does the 567BAA002604ACG require external programming after soldering?

No, the 567BAA002604ACG is fully factory-programmed before shipment. All parameters - including its four specific frequencies, output format (LVPECL), OE polarity (active-high on Pin 2), and tuning slope (60 ppm/V) - are stored in on-chip NVM and operational immediately upon power-up with no I²C or SPI interface required.

What is the absolute pull range (APR) of the 567BAA002604ACG?

The 567BAA002604ACG has a minimum APR of ±20 ppm at 3.3 V, calculated from its 60 ppm/V tuning slope, initial accuracy, temperature stability (±20 ppm), load pulling, VDD variation, and 20-year aging. This APR ensures reliable lock to reference clocks with up to ±20 ppm total instability over full life and temperature range.

Can the 567BAA002604ACG operate at 1.8 V supply?

Yes, the 567BAA002604ACG supports 1.8 V ±5% operation (1.71–1.89 V), delivering full specification performance including 100 fs jitter and 350 ps rise/fall time. Supply current is reduced to ~95 mA (CMOS) or ~100 mA (LVDS) at 1.8 V, enabling use in power-constrained edge AI and portable test equipment.

How is frequency selection implemented on the 567BAA002604ACG?

Frequency selection on the 567BAA002604ACG is performed using two dedicated logic inputs: FS1 (Pin 7) and FS0 (Pin 8). These pins accept CMOS-level signals with internal 50 kΩ pull-ups to VDD, selecting one of four factory-programmed frequencies (FS[1:0] = 00, 01, 10, or 11) with 10 ms settling time after change.
