Product details

Overview

511FAA-BBAG from Skyworks Solutions is a factory-programmed, low-jitter crystal oscillator (XO) with DSPLL-based frequency synthesis, delivering 100 kHz to 250 MHz output across ±30 ppm total stability (including 10-year aging), 3.3 V supply, LVPECL output, and –40°C to +85°C operation in a 5 × 7 mm 6-pin package. It serves as a high-reliability clock source for PCIe Gen3/Gen4 and telecom line cards requiring sub-1.3 ps RMS period jitter.

For engineers reviewing the 511FAA-BBAG datasheet, 511FAA-BBAG pinout, 511FAA-BBAG application, or 511FAA-BBAG equivalent, this page delivers verified technical context, validated pin functions, confirmed timing performance metrics, and real-world deployment guidance for high-speed serial interface clocking systems.

Technical Context

The 511FAA-BBAG implements Skyworks' DSPLL architecture with a fixed internal crystal and digital synthesizer, enabling any-frequency generation without custom crystals. Its on-chip LDO regulator provides supply noise rejection up to 3.5 ps additive jitter at 1 MHz noise injection.

This device uses LVPECL differential output with 0.55–0.90 V_PPSE swing, 100–565 ps rise/fall time, and 48–52% duty cycle. OE is active-high on Pin 1, with internal pull-up, and startup time is ≤10 ms from minimum V_DD.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
Si510FBA-BBAG	Same Si510/511 family, CMOS output, 4-pin 5 × 7 mm package, max 212.5 MHz, no differential pair	Limited to single-ended loads; unsuitable for PCIe or SONET where differential signaling is mandatory	Select only for cost-sensitive, low-speed control-plane clocking where LVPECL noise immunity is unnecessary
MAX2667ETA+	Analog Devices XO; 100 kHz–250 MHz; ±50 ppm stability; 2.5 V LVDS; 3.2 × 5 mm package	Higher stability grade tolerance (±50 ppm vs. ±30 ppm); lower supply voltage; smaller footprint but different pinout	Choose when board space is constrained and ±50 ppm total stability suffices for non-Stratum-3 applications

Compared with 511FAA-BBAG, Si510FBA-BBAG trades differential integrity for reduced pin count and cost, while MAX2667ETA+ offers smaller size at the expense of tighter stability and supply voltage compatibility-making 511FAA-BBAG optimal for high-reliability, high-speed serial infrastructure.

FAQ

What output format and supply voltage does the 511FAA-BBAG use?

The 511FAA-BBAG uses LVPECL output format and operates at 3.3 V ±10%. Its datasheet specifies 0.55–0.90 V_PPSE swing, 100–565 ps rise/fall time, and V_OC = V_DD − 1.4 V. This configuration is factory-programmed and cannot be changed post-shipment. The 511FAA-BBAG is fully compliant with LVPECL interface standards for PCIe and SONET applications.

Does the 511FAA-BBAG support differential output, and how is it implemented?

Yes, the 511FAA-BBAG supports true differential LVPECL output via dedicated CLK+ and CLK− pins (Pins 4 and 5). It requires 50 Ω termination to V_DD − 2 V on each leg and delivers 48–52% duty cycle with ≤1.3 ps RMS period jitter at 156.25 MHz. This implementation meets PCIe Gen3+ and SONET OC-192 jitter masks without external buffering.

What is the total frequency stability specification for the 511FAA-BBAG, and what does it include?

The 511FAA-BBAG has ±30 ppm total stability, which includes initial calibration accuracy, operating temperature variation (–40°C to +85°C), supply voltage change, load variation, mechanical shock/vibration effects, and 10 years of aging at 40°C. This comprehensive spec eliminates need for field recalibration and supports 15+ year product deployments in telecom infrastructure.

How is output enable (OE) configured on the 511FAA-BBAG, and what happens when disabled?

The 511FAA-BBAG has OE active-high on Pin 1 with an internal pull-up resistor (~45 kΩ). When OE is low, outputs enter high-impedance tristate mode within ≤5 µs (for f_O ≥10 MHz). Runt suppression prevents spurious edges during power-up or OE transitions. This behavior is confirmed in Tables 1 and 2 of the Si510/511 datasheet Rev. 1.4.

Is the 511FAA-BBAG pin-compatible with other Si510/511 variants, and what package does it use?

Yes, the 511FAA-BBAG uses the standard 6-pin 5 × 7 mm CLCC package shared across Si511 LVPECL/LVDS/HCSL variants. Pin 1 = OE (active-high), Pin 2 = NC, Pin 3 = GND, Pin 4 = CLK+, Pin 5 = CLK−, Pin 6 = V_DD. This footprint matches industry-standard XO land patterns per IPC-7351 and supports drop-in replacement within the same output format and voltage family.
