Product details

Overview

511ECB-ABAG 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, LVDS output, and operation from –40°C to +85°C in a 5 × 7 mm surface-mount package. It serves as a high-reliability timing source for PCIe, Gigabit Ethernet, and FPGA clocking.

For engineers reviewing the 511ECB-ABAG datasheet, 511ECB-ABAG pinout, 511ECB-ABAG application, or 511ECB-ABAG equivalent, this page provides verified pin functions, real-world jitter performance (0.25 ps RMS phase jitter, 12 kHz–20 MHz), package dimensions, differential LVDS drive capability, and validated alternatives for timing-critical embedded and telecom designs.

Technical Context

The 511ECB-ABAG implements Skyworks' DSPLL architecture with a fixed internal crystal and digital synthesizer, enabling any-frequency programmability without custom crystals. Its on-chip LDO regulator provides supply noise rejection up to 3.5 ps added jitter at 1 MHz 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). Startup time is ≤10 ms, and disable/enable times are ≤5 µs and ≤20 µs respectively for frequencies ≥10 MHz.

Key Specifications

Parameter	Value and Actual Design Meaning
Nominal Frequency	Configured at factory; supports 100 kHz to 250 MHz - enables single-part flexibility across multiple system clock domains.
Output Format	LVDS - delivers low-noise, low-power differential signaling compatible with FPGA and ASIC clock inputs.
Total Stability	±30 ppm - includes initial accuracy, temperature, voltage, load, shock/vibration, and 10-year aging at 40°C.
Supply Voltage	3.3 V ±10% - powers internal LDO and output buffer; supports standard logic rail with noise filtering.
Phase Jitter (RMS)	0.25 ps (1.875 MHz–20 MHz) - meets stringent jitter requirements for PCIe Gen3/Gen4 and 10G Ethernet SerDes.
Operating Temperature	–40°C to +85°C - qualified for industrial and telecom infrastructure environments without derating.
Package	5 × 7 mm, 6-pin SMD - industry-standard footprint with pin 1 = OE, pins 4/5 = CLK+/CLK−, pin 6 = VDD.

Pinout & Package

511ECB-ABAG uses a 6-pin, 5 × 7 mm surface-mount ceramic package (CLCC). Pin 1 is Output Enable (OE), pin 2 is NC, pin 3 is GND, pins 4 and 5 are complementary LVDS outputs (CLK+, CLK−), and pin 6 is VDD.

Pin/Terminal	Circuit Role	Design Meaning
1	OE	Active-high output enable with internal pull-up; asserts high to enable LVDS output; low disables output to high-impedance state.
2	NC	No connect - must remain unconnected per design; no internal circuitry or function.
3	GND	Electrical and case ground reference for all internal circuits and output drivers.
4	CLK+	Positive LVDS output terminal; delivers differential clock signal referenced to CLK− with 100 Ω line-line termination.
5	CLK−	Negative LVDS output terminal; forms true differential pair with CLK+ for common-mode noise rejection.
6	VDD	3.3 V power supply input; feeds internal LDO regulator and output buffer; requires local 100 nF decoupling.

Key Features

Feature	Design Value
DSPLL Any-Frequency Synthesis	Eliminates need for custom crystals - one device covers 100 kHz–250 MHz, reducing BOM count and inventory complexity.
On-Chip LDO Regulator	Provides >30 dB supply noise rejection, limiting added jitter to ≤3.5 ps even under 100 mV_PP 1 MHz VDD noise.
Production-Tested Crystal ESR & DLD	Guarantees long-term reliability and frequency stability by screening resonator quality during manufacturing.
LVDS Output Compliance	Meets JEDEC JESD8-12 standards: 0.25–0.45 V_PPSE, 48–52% duty cycle, 350–800 ps edge rates, 100 Ω differential termination.
Runt Suppression	Prevents partial clock pulses during power-on and OE transitions - ensures clean startup and glitch-free enable/disable.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
Si510ECB-ABAG	Same Si510/511 family, but 4-pin CMOS variant (OE on pin 1, single-ended CLK); max 212.5 MHz; no differential output.	Limited to single-ended loads; unsuitable for LVDS-requiring SerDes interfaces; lower jitter tolerance than LVDS path.	Select only if system uses CMOS clock inputs and frequency ≤212.5 MHz; not drop-in for 511ECB-ABAG due to pinout and interface mismatch.
AK2-156.250MHZ-EFE-T	Fixed-frequency 156.25 MHz LVDS XO; ±25 ppm temp stability only (no 10-year aging spec); no factory-programmable OE polarity.	Not programmable - requires exact frequency match; lacks DSPLL flexibility and total stability guarantee across lifetime.	Use when 156.25 MHz is fixed and cost sensitivity outweighs programmability and long-term stability assurance.

Compared with Si510ECB-ABAG and AK2-156.250MHZ-EFE-T, 511ECB-ABAG uniquely combines factory-configurable LVDS output, ±30 ppm total stability including aging, and DSPLL-based any-frequency synthesis - making it optimal for scalable, long-lifecycle telecom and datacenter timing.

FAQ

What output format and supply voltage does the 511ECB-ABAG use?

The 511ECB-ABAG is configured as an LVDS oscillator operating from a 3.3 V supply. Its differential outputs (CLK+, CLK−) meet JEDEC LVDS specifications with 0.25–0.45 V_PPSE swing and 100 Ω line-line termination. The part ships fully programmed - no external configuration is required.

Does the 511ECB-ABAG include integrated runt suppression?

Yes, the 511ECB-ABAG incorporates runt suppression on both power-on and OE transitions. This prevents partial clock pulses that could cause metastability or false triggering in downstream logic, ensuring clean, glitch-free clock activation critical for PCIe and Ethernet link initialization.

What is the total frequency stability specification for the 511ECB-ABAG?

The 511ECB-ABAG has a total stability of ±30 ppm, which explicitly includes initial calibration error, temperature variation (–40°C to +85°C), supply voltage change, load variation, mechanical stress (shock/vibration), and 10 years of aging at 40°C - verified per Skyworks Rev. 1.4 datasheet Table 2.

Can the 511ECB-ABAG be used in place of a fixed-frequency LVDS oscillator?

Yes - the 511ECB-ABAG is factory-programmed to a specific frequency (e.g., 156.25 MHz) and functions identically to a fixed-frequency LVDS XO in circuit. Its DSPLL core ensures identical electrical behavior, jitter performance, and pin compatibility with standard 5 × 7 mm LVDS oscillators.

What is the startup time and enable/disable timing for the 511ECB-ABAG?

The 511ECB-ABAG achieves full-frequency accuracy within ≤10 ms after VDD reaches minimum (2.97 V). For frequencies ≥10 MHz, output disable time (TD) is ≤5 µs and enable time (TE) is ≤20 µs - measured from OE transition to valid clock edges meeting duty cycle and amplitude specs.
