Product details

Overview

510RAB-BBAG from Skyworks Solutions is a factory-programmed, low-jitter crystal oscillator (XO) based on DSPLL technology, delivering 100 kHz to 250 MHz output frequency with ±30 ppm total stability (including 10-year aging), 3.3 V supply, LVDS output, and –40°C to +85°C operation in a 5 × 7 mm package. It serves as a precision clock source for high-speed serial interfaces requiring deterministic jitter performance.

For engineers reviewing the 510RAB-BBAG datasheet, 510RAB-BBAG pinout, 510RAB-BBAG application, or 510RAB-BBAG equivalent, this device offers configurable frequency, industry-standard LVDS signaling, integrated LDO noise filtering, and production-tested crystal ESR/DLD - critical for PCIe Gen4/5, 10G Ethernet, and FPGA timing integrity validation.

Technical Context

The 510RAB-BBAG implements Skyworks' DSPLL architecture with a fixed internal crystal and digital synthesis, enabling any frequency across 100 kHz–250 MHz without custom crystals. Its LVDS output delivers 0.25–0.55 ps RMS phase jitter (1.875–20 MHz integration) and 0.25–0.55 V_PPSE swing into 100 Ω differential termination.

It features an on-chip LDO regulator for supply noise rejection, OE pin with internal pull-up (active-high), and runt suppression on power-up and OE assertion. Startup time is ≤10 ms; enable/disable times are ≤20 µs (≥10 MHz) and ≤60 µs (＜10 MHz).

Key Specifications

Parameter	Value and Actual Design Meaning
Output Frequency Range	100 kHz to 250 MHz - supports arbitrary frequencies without crystal change; enables single-BOM flexibility across multiple designs.
Total Stability	±30 ppm - includes initial accuracy, temperature, voltage, load, shock/vibration, and 10-year aging at 40°C; ensures long-term system timing margin.
Supply Voltage	3.3 V ±10% - compatible with standard logic rails; internal LDO maintains regulation under noisy supply conditions.
Output Format	LVDS - differential signaling with 100 Ω line-line termination; provides noise immunity and <2.1 ps RMS period jitter.
Operating Temperature	–40°C to +85°C - qualified for industrial and telecom infrastructure environments without derating.
Package	5 × 7 mm, 6-pin - industry-standard footprint; pin-compatible with other Si510/511 variants in same package size.
Phase Jitter (RMS)	0.25 ps (1.875–20 MHz) - meets stringent requirements for 10G/25G Ethernet and PCIe Gen4 reference clocks.

Pinout & Package

510RAB-BBAG uses the Si510 6-pin, 5 × 7 mm package with LVDS output configuration (OE on Pin 2). The package is RoHS-compliant, Pb-free, and features gold-over-nickel contact pads.

Pin/Terminal	Circuit Role	Design Meaning
1	NC	No connect - must remain unconnected; floating or tied to GND may impair performance.
2	OE	Output Enable (active-high, internal pull-up) - controls LVDS output state; runt-suppressed for glitch-free enable/disable.
3	GND	Electrical and case ground - dedicated return path for output and supply currents; requires low-impedance PCB plane.
4	CLK+	Differential LVDS positive output - referenced to CLK–; requires controlled 100 Ω differential impedance routing.
5	CLK–	Differential LVDS complementary output - 180° out-of-phase with CLK+; matched length routing essential.
6	VDD	3.3 V power supply input - filtered by internal LDO; decoupling capacitor (0.1 µF + 4.7 µF) required near pin.

Key Features

Feature	Design Value
DSPLL-based Any-Frequency Synthesis	Eliminates need for custom crystals; enables one-time programming of exact frequency during manufacturing - reduces NRE and lead time.
On-Chip LDO Regulator	Provides >3.0 ps/mV supply noise rejection at 100–500 kHz; simplifies board-level power filtering for low-jitter clock generation.
Production-Tested Crystal ESR & DLD	Guarantees reliability and stability over life; prevents field failures due to crystal degradation or mechanical stress.
Runt Suppression on OE and Power-On	Prevents false clock edges during power sequencing or software-controlled enable - critical for synchronous FPGA/ASIC startup.
Industry-Standard 5 × 7 mm Package	Enables drop-in replacement for legacy XOs; compatible with automated SMT assembly and IPC-7351 land patterns.

FAQ

What output format and supply voltage does the 510RAB-BBAG use?

The 510RAB-BBAG uses LVDS output format and operates at 3.3 V ±10%. Its LVDS driver is specified for 100 Ω differential termination and delivers 0.25–0.55 V_PPSE swing. The device integrates an on-chip LDO regulator to maintain stable core operation despite supply ripple - a key feature confirmed in Skyworks' Si510/511 Rev. 1.4 datasheet Table 3 and Section 1.

What is the total frequency stability specification for the 510RAB-BBAG?

The 510RAB-BBAG has a total frequency stability of ±30 ppm, which includes initial calibration accuracy, temperature variation (–40°C to +85°C), supply voltage change, load variation, mechanical shock/vibration, and 10-year aging at 40°C. This value is explicitly defined in Table 2 of the Skyworks Si510/511 datasheet Rev. 1.4 under "Frequency Stability Grade C".

Does the 510RAB-BBAG support differential or single-ended clock outputs?

The 510RAB-BBAG supports differential LVDS output only - it provides complementary CLK+ and CLK– signals requiring 100 Ω line-line termination. It does not support single-ended CMOS or other formats. Pin assignments confirm Pins 4 and 5 as CLK+ and CLK–, with Pin 1 as NC and Pin 2 as OE, per Table 12 in the Si510/511 datasheet Rev. 1.4.

What package type and dimensions does the 510RAB-BBAG use?

The 510RAB-BBAG uses a 5 × 7 mm, 6-pin surface-mount package with industry-standard outline and land pattern per Figures 6 and 7 in the Si510/511 datasheet Rev. 1.4. Dimensions include nominal body size 5.00 × 7.00 mm, height 0.65 mm, and 2.54 mm pin pitch - fully compatible with automated placement and IPC-7351 design rules.

Is the 510RAB-BBAG pin-compatible with other Si510/511 variants in the same package?

Yes, the 510RAB-BBAG is pin-compatible with all Si510/511 6-pin, 5 × 7 mm variants sharing the same pinout: Pin 2 = OE (active-high), Pins 4/5 = CLK+/CLK–, Pin 6 = VDD, Pin 3 = GND, and Pin 1 = NC. This compatibility is verified in Tables 12 and 13 and functional diagrams on pages 12–13 of the Skyworks Si510/511 datasheet Rev. 1.4.
