Skyworks Solutions Inc. 530BC125M000DG

Overview

530BC125M000DG from Skyworks Solutions is a factory-programmed, low-jitter crystal oscillator (XO) delivering 125.000 MHz output in LVDS format with ±7 ppm temperature stability and 3.3 V supply. It uses DSPLL® synthesis for superior supply noise rejection and operates across –40 °C to +85 °C. This device serves as a primary clock source in high-speed FPGA and networking equipment requiring stable, low-phase-noise timing.

For engineers reviewing the 530BC125M000DG datasheet, 530BC125M000DG pinout, 530BC125M000DG application, or 530BC125M000DG equivalent, key selection criteria include its 0.36 ps RMS phase jitter (12 kHz–20 MHz), LVDS differential output compliance, 5 × 7 mm industry-standard package, and factory-configured OE-active-high enable logic.

Technical Context

The 530BC125M000DG implements Skyworks' third-generation DSPLL® architecture, synthesizing 125 MHz from a fixed internal crystal to achieve high frequency stability and low aging (±3 ppm first-year drift). Its LVDS output stage delivers 0.5–0.9 V_PP differential swing into 100 Ω, with 45–55% duty cycle symmetry and sub-350 ps rise/fall times.

It features an integrated 17 kΩ pull-up resistor on the OE pin, enabling default-enabled operation without external biasing. Power-up time is ≤10 ms, and supply current is 90 mA typical under enabled LVDS output at 3.3 V - optimized for dense, thermally constrained communication system PCBs.

FAQ

What output format and voltage does the 530BC125M000DG use?

The 530BC125M000DG is configured for LVDS output at 3.3 V supply. Its differential CLK+/CLK– outputs deliver 0.5–0.9 V_PP swing into a 100 Ω load, with 45–55% duty cycle symmetry and sub-350 ps edge rates - confirmed in Table 3 of the Si530/531 datasheet Rev. 1.5.

Is the 530BC125M000DG pin-compatible with other Si530-series oscillators?

Yes, the 530BC125M000DG uses the standard Si530 LVDS/LVPECL/CML pinout (OE on pin 1, NC on pin 2, GND on pin 3, CLK+ on pin 4, CLK– on pin 5, VDD on pin 6), matching all Si530 variants in the 5 × 7 mm package - verified in Table 10 and Figure 2 of the datasheet.

What is the phase jitter performance of the 530BC125M000DG at 125 MHz?

The 530BC125M000DG delivers 0.36 ps RMS phase jitter (12 kHz–20 MHz) and 0.34 ps RMS (50 kHz–80 MHz), as specified in Table 4 for FOUT = 125–500 MHz. This meets OC-48/OC-192 jitter compliance thresholds and supports high-speed serial link timing budgets.

Does the 530BC125M000DG require external configuration or programming?

No - the 530BC125M000DG is factory-programmed for 125.000 MHz, LVDS output, ±7 ppm stability, 3.3 V supply, and OE-active-high polarity. It operates immediately upon power-up with no I²C, SPI, or external EEPROM required - per Section 3 and Figure 1 of the datasheet.

What is the operating temperature range and reliability qualification for the 530BC125M000DG?

The 530BC125M000DG is rated for –40 °C to +85 °C operation and qualified to MIL-STD-883 mechanical shock/vibration, J-STD-020 MSL1 moisture sensitivity, and JEDEC soldering profiles - documented in Tables 7–9 and Section 6 of the Si530/531 datasheet Rev. 1.5.
