Product details
Overview
511FAB-BBAG from Skyworks Solutions is a factory-programmed, low-jitter crystal oscillator (XO) based on DSPLL technology, delivering 100 MHz output with ±30 ppm total stability (including 10-year aging), 3.3 V supply, LVDS output, and operation from –40 °C to +85 °C in a 5 × 7 mm surface-mount package. It serves as a precision clock source for high-speed serial interfaces requiring deterministic jitter performance.
For engineers reviewing the 511FAB-BBAG datasheet, 511FAB-BBAG pinout, 511FAB-BBAG application, or 511FAB-BBAG equivalent, this page provides verified technical context, validated pin functions, confirmed LVDS timing specifications, and real-world deployment guidance for telecom, datacom, and FPGA clocking systems.
Technical Context
The 511FAB-BBAG implements Skyworks' DSPLL architecture with a fixed internal crystal and digital synthesis to generate stable 100 MHz LVDS output across temperature, voltage, and load variations. Its on-chip LDO regulator ensures >3.5 ps RMS additive jitter rejection against 100–1 MHz supply noise.
It features active-high OE control on Pin 1, complementary differential outputs (CLK+/CLK−), and full production test coverage including crystal ESR and DLD validation - guaranteeing reliability in mission-critical timing applications without custom crystal procurement.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Nominal Frequency | 100 MHz - precisely factory-programmed; supports PCIe Gen3/Gen4 reference clock requirements. |
| Output Format | LVDS - differential signaling with 350–800 ps rise/fall time, enabling noise-immune board-level distribution. |
| Total Stability | ±30 ppm - includes initial accuracy, temp/voltage/load variation, shock/vibration, and 10-year aging at 40 °C. |
| Supply Voltage | 3.3 V ±10% - compatible with standard logic rails; internal LDO filters supply noise to limit jitter degradation. |
| Phase Jitter (12 kHz–20 MHz) | 0.8–1.0 ps RMS - meets SONET OC-192 and 10G Ethernet jitter budgets. |
| Operating Temperature | –40 °C to +85 °C - qualified per MIL-STD-883 for industrial and telecom infrastructure environments. |
| Package | 5 × 7 mm, 6-pin SMD - industry-standard footprint with GND, VDD, OE, CLK+, CLK−, and NC pins. |
Pinout & Package
511FAB-BBAG uses a 6-pin, 5 × 7 mm surface-mount ceramic package (CLCC). Pin 1 is OE (active-high), Pin 2 is NC, Pin 3 is GND, Pin 4 is CLK+, Pin 5 is CLK−, and Pin 6 is VDD. The package complies with RoHS, Pb-free, and JEDEC J-STD-020E reflow standards.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OE (Output Enable) | Active-high control input; internal pull-up resistor enables default output assertion on power-up. |
| 2 | NC | No connect - must remain unconnected per design; no internal circuitry attached. |
| 3 | GND | Electrical and case ground reference for all analog/digital blocks and output drivers. |
| 4 | CLK+ | Differential positive clock output; paired with CLK− to deliver LVDS-compliant 350–800 ps edge rates. |
| 5 | CLK− | Differential negative clock output; maintains 180° phase relationship with CLK+ for common-mode noise rejection. |
| 6 | VDD | 3.3 V main supply input; powers DSPLL core, output drivers, and integrated LDO regulator. |
Key Features
| Feature | Design Value |
|---|---|
| DSPLL-based frequency synthesis | Enables single-part support for any frequency from 100 kHz to 250 MHz without custom crystals. |
| On-chip LDO regulator | Provides >3.5 ps RMS supply-noise rejection, eliminating need for external filtering in noisy power domains. |
| Production-tested crystal ESR & DLD | Guarantees long-term stability and mechanical robustness under thermal cycling and vibration stress. |
| Runt suppression on OE and power-on | Prevents false clock edges during enable transitions or brown-out conditions, ensuring clean system reset behavior. |
| Factory-programmed configuration | Ships fully configured - no field programming required; eliminates NRE charges and 2–4 week lead times of custom XOs. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar XO applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Si510FAB-BBAG | CMOS output (single-ended), same 100 MHz, ±30 ppm, 3.3 V, 5 × 7 mm package. | Limited to lower-speed interfaces (e.g., USB 2.0, legacy PCI); not suitable for LVDS-requiring SerDes. | Select when board layout lacks differential routing capability or cost-sensitive CMOS loads dominate. |
| Si530-100M000 | Ultra-low jitter (0.23 ps RMS), but fixed 100 MHz, no programmability, higher cost, same 5 × 7 mm footprint. | Targeted for ultra-low-jitter applications (e.g., RF sampling clocks); over-specified for standard datacom use. | Choose only if phase jitter <0.3 ps RMS is mandatory and budget allows premium pricing. |
Compared with Si510FAB-BBAG, 511FAB-BBAG enables differential signaling for noise immunity in dense PCBs, while Si530-100M000 offers superior jitter at higher cost and zero configurability - making 511FAB-BBAG the optimal balance of performance, flexibility, and value for LVDS-based infrastructure designs.

FAQ
What output format and supply voltage does the 511FAB-BBAG use?
The 511FAB-BBAG is configured for LVDS output and 3.3 V supply, as indicated by the "F" (3.3 V LVDS) and "A" (±30 ppm stability) codes in its part number. It delivers differential 100 MHz clock signals compliant with ANSI TIA/EIA-644-A LVDS standards, with typical supply current of 19–23 mA under enabled conditions.
Does the 511FAB-BBAG require external configuration or programming after soldering?
No, the 511FAB-BBAG is factory-programmed and fully functional upon power-up. All parameters - including 100 MHz frequency, LVDS output, ±30 ppm stability, 3.3 V operation, active-high OE, and 5 × 7 mm package - are permanently configured before shipment. No I²C, SPI, or other interface is present or needed.
What is the startup time and enable/disable timing behavior of the 511FAB-BBAG?
The 511FAB-BBAG achieves full-frequency stability within ≤10 ms after VDD reaches minimum specification. When OE is asserted (high), output enables in ≤20 µs for 100 MHz operation; when OE is deasserted (low), output disables in ≤5 µs. Runt suppression prevents spurious edges during these transitions.
Can the 511FAB-BBAG be used in place of a traditional quartz crystal oscillator?
No - the 511FAB-BBAG is a complete crystal oscillator (XO) module, not a bare crystal. It integrates a fixed crystal resonator, DSPLL synthesizer, output drivers, and LDO regulator into one 5 × 7 mm package. It replaces both discrete crystals and associated oscillator ICs, simplifying BOM and layout.
Is the 511FAB-BBAG pin-compatible with other Si510/511 variants in the same package?
Yes - all 5 × 7 mm, 6-pin Si511 variants (e.g., 511ECB..., 511KAB...) share identical pinout: Pin 1 = OE, Pin 2 = NC, Pin 3 = GND, Pin 4 = CLK+, Pin 5 = CLK−, Pin 6 = VDD. This allows drop-in replacement across frequency, voltage, and stability options without PCB redesign.
