Skyworks Solutions Inc. 531FB200M000DG

Overview

531FB200M000DG from Skyworks Solutions is a factory-programmed, low-jitter crystal oscillator (XO) delivering 200.000 MHz differential LVDS output with ±20 ppm total frequency stability over –40 to +85 °C, 3.3 V supply, and industry-standard 5 × 7 mm 6-pin package. It employs third-generation DSPLL® synthesis for superior supply noise rejection and is used in high-speed networking and FPGA clocking where jitter-sensitive timing is critical.

For engineers reviewing the 531FB200M000DG datasheet, 531FB200M000DG pinout, 531FB200M000DG application, or 531FB200M000DG equivalent, key selection criteria include its 0.36 ps RMS phase jitter (12 kHz–20 MHz), LVDS output compatibility with 100 Ω differential termination, OE-active-high control logic, and qualification per MIL-STD-883 and J-STD-020 MSL1.

Technical Context

The 531FB200M000DG implements Skyworks' DSPLL® architecture with a fixed internal crystal resonator, enabling stable 200 MHz output without external crystal tuning. Its PLL-based synthesis provides deterministic jitter performance independent of supply rail noise, supporting reliable operation in dense PCB environments.

This Si531-series device uses pin 1 for OE (active-high), pin 3 for GND, pin 4 for CLK+, pin 5 for CLK–, and pin 6 for VDD - matching the LVDS/LVPECL/CML pinout variant. It supports tristate mode via OE, achieves 10 ms power-up time, and maintains ≤±20 ppm total stability including aging and temperature effects.

FAQ

What output format and voltage does the 531FB200M000DG provide?

The 531FB200M000DG provides LVDS output with a nominal 1.20 V common-mode voltage and 0.7 VPP differential swing, operating from a 3.3 V supply (2.97–3.63 V range). This matches standard LVDS interface requirements and ensures compatibility with FPGA transceivers and SERDES PHYs without level-shifting circuitry.

How is frequency stability specified for the 531FB200M000DG?

The 531FB200M000DG specifies ±20 ppm total frequency stability, which includes ±7 ppm temperature variation over –40 to +85 °C, ±3 ppm aging over the first year, and margin for initial calibration error. This value is confirmed in Table 2 of the Skyworks Si530/531 datasheet Rev. 1.5 and applies directly to the 531FB200M000DG configuration.

Does the 531FB200M000DG support tristate functionality, and how is it controlled?

Yes, the 531FB200M000DG supports tristate via its OE (Output Enable) pin (pin 1), which is active-high. When OE is logic low, both CLK+ and CLK– outputs enter high-impedance state, reducing supply current from ~90 mA to ~60 mA. An internal 17 kΩ pull-up resistor ensures outputs enable automatically at power-up unless actively driven low.

What is the phase jitter performance of the 531FB200M000DG at 200 MHz?

The 531FB200M000DG delivers 0.36 ps RMS phase jitter measured over the 12 kHz to 20 MHz offset band (OC-48 condition), as specified in Table 4 of the Skyworks Si530/531 datasheet. This performance is guaranteed for the 200 MHz LVDS output and enables compliance with stringent telecom and datacom timing standards.

Is the 531FB200M000DG pin-compatible with other Si53x oscillators?

The 531FB200M000DG uses the Si531 pinout (OE on pin 1), differing from Si530 variants that place OE on pin 2. While both share the same 5 × 7 mm package and pin count, direct PCB substitution requires verification of OE routing. The 531FB200M000DG is not pin-compatible with Si530-series parts without layout modification.
