Product details

Overview

511FAA-ABAG from Skyworks Solutions is a factory-programmed, low-jitter crystal oscillator (XO) delivering 100 MHz output with ±30 ppm total stability (including 10-year aging), 3.3 V CMOS output, and operation from –40 °C to +85 °C in a 5 × 7 mm surface-mount package. It uses DSPLL synthesis for frequency flexibility and integrates an on-chip LDO for supply noise rejection - deployed in FPGA clocking, Gigabit Ethernet PHYs, and telecom line cards.

For engineers reviewing the 511FAA-ABAG datasheet, 511FAA-ABAG pinout, 511FAA-ABAG application, or 511FAA-ABAG equivalent, this page provides verified technical context, real-world design meaning of key specs, validated pin functions, confirmed application use cases, and two field-tested alternative options - all grounded in Skyworks' Si511 family documentation and ordering data.

Technical Context

The 511FAA-ABAG implements Skyworks' DSPLL architecture with a fixed internal crystal and digital synthesizer, enabling precise 100 MHz generation without custom crystals. Its CMOS output drives 15 pF loads with 0.45–1.2 ns rise/fall time and 48–52% duty cycle.

It features an active-high OE pin (pin 1), internal pull-up resistor (~45 kΩ), and integrated LDO regulator that filters supply noise - contributing to 0.25–0.35 ps RMS phase jitter (1.875–20 MHz integration) and 3.0–3.5 ps additive jitter from 10–1000 kHz VDD noise.

Key Specifications

Parameter	Value and Actual Design Meaning
Output Frequency	100 MHz - stable reference for PCIe Gen1/2 root complexes and Ethernet MAC timing
Total Stability	±30 ppm - includes initial tolerance, temp, voltage, load, shock/vibration, and 10-year aging at 40 °C
Supply Voltage	3.3 V ±10% - compatible with standard I/O rails; supports 21 mA typical supply current
Output Format	CMOS - single-ended, rail-to-rail swing, 8 mA drive strength into 50 Ω
Package	5 × 7 mm, 4-pin SMD - industry-standard footprint with GND/VDD/CLK/OE layout
Operating Temp	–40 °C to +85 °C - qualified for industrial and telecom infrastructure environments
Phase Jitter	0.25 ps RMS (1.875–20 MHz) - meets SONET OC-48 and 10GBase-R jitter budgets

Pinout & Package

511FAA-ABAG uses the Si511 4-pin CMOS configuration in a 5 × 7 mm CLCC package (lead-free, RoHS compliant). Pin 1 = OE (active high, internal pull-up), Pin 2 = GND, Pin 3 = CLK (CMOS output), Pin 4 = VDD (3.3 V).

Pin/Terminal	Circuit Role	Design Meaning
1	OE	Output Enable - logic high enables CLK; internal ~45 kΩ pull-up ensures default enabled state at power-up
2	GND	Electrical and case ground - must be connected to low-impedance system ground plane
3	CLK	CMOS clock output - 0.85×VDD high / 0.15×VDD low, 0.45–1.2 ns edge rate, 48–52% duty cycle
4	VDD	Power supply input - accepts 2.97–3.63 V; powers internal DSPLL, LDO, and output buffer

Key Features

Feature	Design Value
DSPLL-based synthesis	Enables factory-programmed 100 MHz without custom crystal - eliminates long lead times and NRE charges
On-chip LDO regulator	Rejects >30 dB of supply noise up to 1 MHz, reducing need for external filtering in noisy DC/DC domains
Runt suppression	Prevents partial-clock pulses during power-up and OE transitions - avoids metastability in synchronous logic
Production-tested crystal ESR/DLD	Guarantees start-up reliability and long-term stability - no field failures due to resonator degradation
10-year aging inclusion	Total ±30 ppm spec covers full product lifetime - simplifies system-level timing margin analysis

Equivalent & Alternatives

The following parts are listed as comparable options for similar oscillator applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
Si510CAA-ABAG	Same Si511 family, but Si510 variant - OE on pin 2 instead of pin 1; identical 100 MHz/±30 ppm/3.3 V CMOS spec	Requires PCB layout change: OE moves from pin 1 to pin 2; same 5 × 7 mm footprint	Select if existing board uses Si510 pinout or requires OE on pin 2 for routing optimization
SG-8018CE 100.000000MHz	Standard quartz XO (not DSPLL); ±50 ppm stability; 2.5 V CMOS; 3.2 × 2.5 mm package	Lacks DSPLL flexibility, LDO noise rejection, and 10-year aging guarantee; smaller footprint	Choose for cost-sensitive, non-critical timing where ±50 ppm and no LDO are acceptable

Compared with Si510CAA-ABAG, 511FAA-ABAG offers identical electrical performance but places OE on pin 1 - simplifying control-line routing in new designs. Versus SG-8018CE, 511FAA-ABAG delivers tighter stability, superior supply noise immunity, and guaranteed long-term aging - critical for telecom and industrial systems.

FAQ

What output format and voltage does the 511FAA-ABAG provide?

The 511FAA-ABAG provides a 3.3 V CMOS output signal at 100 MHz. It uses a single-ended CMOS driver capable of sourcing/sinking 8 mA into a 50 Ω load, with rail-to-rail logic levels (0.15×VDD low, 0.85×VDD high) and 48–52% duty cycle. This matches standard FPGA and ASIC I/O voltage domains without level-shifting.

Is the 511FAA-ABAG pin-compatible with other Si510/511 variants?

The 511FAA-ABAG is pin-compatible with other Si511 4-pin CMOS devices (e.g., 511FBA-ABAG) in the same 5 × 7 mm package, sharing identical pin 1 (OE), pin 2 (GND), pin 3 (CLK), and pin 4 (VDD) assignments. It is not pin-compatible with Si510 variants, which place OE on pin 2, nor with 6-pin differential-output versions.

What is the startup time and enable/disable behavior of the 511FAA-ABAG?

The 511FAA-ABAG has a maximum startup time of 10 ms from VDD ramp to valid 100 MHz output. Its OE pin (active high, internal pull-up) enables the output within ≤20 µs when asserted, and disables it within ≤5 µs for frequencies ≥10 MHz. Runt suppression prevents invalid edges during power-up and OE transitions.

Does the 511FAA-ABAG include aging compensation in its stability specification?

Yes - the ±30 ppm total stability specification for 511FAA-ABAG explicitly includes 10 years of aging at 40 °C, in addition to initial calibration error, temperature drift, supply voltage variation, load change, and mechanical stress effects. This is verified via production testing of crystal ESR and DLD parameters.

Can the 511FAA-ABAG operate from a noisy 3.3 V DC/DC supply?

Yes - the 511FAA-ABAG integrates an on-chip LDO regulator that provides >30 dB supply noise rejection up to 1 MHz. Measured additive jitter from 10–1000 kHz VDD noise is only 3.0–3.5 ps RMS, enabling reliable operation directly from switching regulators without additional LC filtering.
