Product details

Overview

510GAA-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 1.8 V, 2.5 V, or 3.3 V supply. It features ±30 ppm total stability (including 10-year aging), LVDS output format, and operates from –40 °C to +85 °C in a 5 × 7 mm 6-pin package. Used for PCIe clocking, FPGA reference clocks, and telecom line cards where jitter-sensitive timing is critical.

For engineers reviewing the 510GAA-BBAG datasheet, 510GAA-BBAG pinout, 510GAA-BBAG application, or 510GAA-BBAG equivalent, this page provides verified pin functions, real-world jitter performance (0.25 ps RMS phase jitter, 12 kHz–20 MHz), package dimensions, thermal resistance (110 °C/W), and validated alternatives for LVDS XO replacement in high-speed serial interfaces.

Technical Context

The 510GAA-BBAG implements Skyworks' DSPLL architecture with a fixed internal crystal and digital synthesizer, enabling any-frequency output without custom crystals. Its on-chip LDO regulator provides supply noise rejection up to 3.5 ps added jitter at 500 kHz noise injection.

It supports LVDS differential signaling with 0.25–0.45 V_PPSE swing, 48–52% duty cycle, and 350–800 ps rise/fall time (20–80% V_DD). OE pin (Pin 2) enables active-high tristate control with internal pull-up resistor (45 kΩ).

Key Specifications

Parameter	Value and Actual Design Meaning
Nominal Frequency	Configured at factory; supports 0.1–250 MHz range - enables single-part flexibility across multiple system clock domains.
Output Format	LVDS - delivers low-noise, low-power differential signaling compatible with PCIe Gen3/Gen4, SATA, and FPGA I/O banks.
Total Stability	±30 ppm - includes initial accuracy, temperature, voltage, load, shock/vibration, and 10-year aging at 40 °C - ensures long-term timing margin in field-deployed equipment.
Phase Jitter (RMS)	0.25 ps (1.875 MHz–20 MHz) - meets stringent jitter budgets for 10 GbE, OTN, and SerDes applications.
Supply Voltage	3.3 V ±10% - standard industrial rail; supports robust operation under board-level voltage ripple.
Operating Temp	–40 °C to +85 °C - qualified for extended-temperature industrial and telecom infrastructure environments.
Package	5 × 7 mm, 6-pin CLCC - industry-standard footprint with documented land pattern (IPC-7351 compliant) and 110 °C/W θ_JA.

Pinout & Package

510GAA-BBAG uses the Si510 6-pin CLCC package (5 × 7 mm) with LVDS output configuration and OE on Pin 2. The package is RoHS-compliant, Pb-free, and features gold-over-nickel contact pads per MIL-STD-883.

Pin/Terminal	Circuit Role	Design Meaning
1	NC	No connect - must remain unconnected; no internal function or biasing.
2	OE	Output Enable (active high); internal 45 kΩ pull-up - enables hardware-controlled clock gating without external logic.
3	GND	Electrical and case ground - serves as reference for LVDS common-mode (1.13–1.33 V) and return path for output current.
4	CLK+	LVDS positive output - delivers complementary signal referenced to CLK–; requires 100 Ω differential termination.
5	CLK–	LVDS negative output - forms differential pair with CLK+; maintains <100 ps skew over temperature and voltage.
6	VDD	3.3 V power supply - powers DSPLL core, output driver, and integrated LDO; decoupling required per layout guidelines.

Key Features

Feature	Design Value
Any-frequency DSPLL synthesis	Eliminates crystal customization - one BOM item covers 0.1–250 MHz, reducing inventory and NRE for multi-platform designs.
On-chip LDO regulator	Provides >40 dB supply noise rejection - reduces need for ultra-clean power rails and simplifies PCB power delivery network.
Production-tested crystal ESR & DLD	Guarantees start-up reliability and aging performance - avoids field failures due to resonator degradation over 10 years.
Runt suppression on OE and power-on	Prevents false clock edges during enable transitions or brown-out - essential for deterministic FPGA configuration and state-machine reset.
LVDS output with 0.25 ps RMS jitter	Meets PCIe Gen4 and 10G-KR jitter masks - enables direct connection to high-speed SerDes without additional jitter cleaning.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
Si511GAA-BBAG	Same Si510/511 family, but OE on Pin 1 (not Pin 2); identical electrical specs and 5 × 7 mm 6-pin package.	Requires PCB layout change for OE routing; otherwise drop-in functional replacement for systems needing OE on Pin 1.	Select only if existing design uses OE on Pin 1 - pinout differs, but frequency, jitter, and stability match exactly.
AK2-156.250MHZ-EFE-T	156.25 MHz fixed-frequency LVDS XO (no DSPLL); ±25 ppm temp stability only; no 10-year aging spec; 3.3 V only.	Limited to single frequency; lacks programmability and total stability grade C (±30 ppm including aging).	Choose for cost-sensitive, single-frequency applications where long-term drift tolerance is relaxed and DSPLL flexibility is unnecessary.

Compared with Si511GAA-BBAG, 510GAA-BBAG offers identical performance but different OE pin location - requiring layout revision. Against AK2-156.250MHZ-EFE-T, 510GAA-BBAG adds DSPLL programmability, full ±30 ppm total stability, and guaranteed 10-year aging - critical for multi-generation platform reuse and telecom qualification.

FAQ

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

The 510GAA-BBAG is configured as an LVDS oscillator operating from a 3.3 V supply (±10%). Its output delivers differential signals on Pins 4 (CLK+) and 5 (CLK–) with 100 Ω termination, and it includes an active-high OE on Pin 2 with internal pull-up. This matches the "BB" ordering code in the part number syntax.

Does the 510GAA-BBAG include aging compensation in its stability specification?

Yes - the ±30 ppm total stability rating for 510GAA-BBAG explicitly includes 10 years of aging at 40 °C, in addition to initial calibration, temperature variation, supply voltage change, load variation, and mechanical stress. This is defined in Table 2 footnote and qualifies the device for long-life infrastructure deployments.

What is the startup time and disable/enable timing behavior of the 510GAA-BBAG?

The 510GAA-BBAG has a maximum startup time of 10 ms (from minimum V_DD to output within spec), disable time of ≤5 µs (for f_O ≥10 MHz), and enable time of ≤20 µs (for f_O ≥10 MHz). These values are measured under full-spec conditions and support fast power-state transitions in PCIe ASPM and FPGA partial reconfiguration.

Can the 510GAA-BBAG be used with 1.8 V or 2.5 V supplies?

No - the "BB" suffix in 510GAA-BBAG specifies 3.3 V operation. While the Si510/511 family supports 1.8 V and 2.5 V variants, this specific part is factory-programmed for 3.3 V ±10%. Using lower voltages will result in malfunction or failure to meet output drive and jitter specifications.

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

Yes - all Si510/511 5 × 7 mm 6-pin variants share identical mechanical footprint and pin assignments. However, OE position differs between Si510 (Pin 2) and Si511 (Pin 1); 510GAA-BBAG is Si510-series, so OE is on Pin 2, and substitution with Si511 parts requires PCB modification.
