Product details

Overview

511SBA156M250BAG from Skyworks Solutions is a factory-programmed, low-jitter silicon-based crystal oscillator (XO) delivering 156.25 MHz output with ±30 ppm total stability (including 10-year aging), 3.3 V supply, LVDS output format, and operation from –40 °C to +85 °C in a 5 × 7 mm surface-mount package. It serves as a high-reliability clock source for synchronous serial interfaces requiring precise timing.

For engineers reviewing the 511SBA156M250BAG datasheet, 511SBA156M250BAG pinout, 511SBA156M250BAG application, or 511SBA156M250BAG equivalent, this device offers DSPLL-based frequency synthesis, integrated LDO noise filtering, runt suppression on OE, and production-tested crystal ESR/DLD - critical for FPGA/ASIC clocking, Gigabit Ethernet PHYs, and SDI video systems where jitter and supply noise immunity are design-critical.

Technical Context

The 511SBA156M250BAG implements Skyworks' DSPLL architecture with a fixed internal crystal and digital synthesizer, enabling any-frequency generation from 100 kHz to 250 MHz without custom crystals. Its LVDS output operates with 100 Ω differential termination, 0.25–0.45 V_PPSE swing, and 48–52% duty cycle across temperature and voltage.

It integrates an on-chip LDO regulator for supply noise rejection, supports active-high OE with internal pull-up, and features runt suppression during power-on and OE transitions. Startup time is ≤10 ms, disable time ≤5 µs (for f_O ≥10 MHz), and enable time ≤20 µs under same condition.

Key Specifications

Parameter	Value and Actual Design Meaning
Output Frequency	156.25 MHz - precisely matches IEEE 802.3 standard for 10GBASE-R and SMPTE ST 292/424 HD-SDI reference clocks.
Total Stability	±30 ppm - includes initial accuracy, temp, voltage, load, shock/vibration, and 10-year aging at 40 °C; enables long-term system timing compliance without recalibration.
Output Format	LVDS - differential signaling with 100 Ω line-line termination, 0.35 V_PPSE typical swing, and <2.1 ps RMS period jitter for robust noise immunity in dense PCB layouts.
Supply Voltage	3.3 V ±10% - compatible with standard logic rails; draws 19–23 mA (typ.) when enabled, supporting low-power system-level power budgeting.
Operating Temp	–40 °C to +85 °C - qualified for industrial and telecom infrastructure environments without derating or thermal management overhead.
Package	5 × 7 mm, 6-pin SMD - industry-standard footprint with pin 1 = OE, pin 3 = GND, pin 4 = CLK+, pin 5 = CLK−, pin 6 = VDD; enables drop-in replacement of legacy LVDS XOs.

Pinout & Package

511SBA156M250BAG uses a 6-pin, 5 × 7 mm surface-mount ceramic package (CLCC). Pin assignments follow Si511 LVDS/LVPECL/HCSL configuration with OE on pin 1.

Pin/Terminal	Circuit Role	Design Meaning
1	OE (Output Enable)	Active-high control with internal pull-up; asserts runt suppression during assertion/deassertion and ensures glitch-free startup/shutdown.
2	NC	No connect - must remain unconnected per datasheet; no internal circuitry or bond wire attached.
3	GND	Electrical and case ground reference; requires low-inductance connection to system ground plane to maintain LVDS common-mode integrity.
4	CLK+	Differential positive clock output; routed with matched length and 100 Ω controlled impedance to receiver's LVDS input.
5	CLK−	Differential negative clock output; complementary to CLK+; pair must be tightly coupled (≤5 mil spacing) to minimize skew and EMI.
6	VDD	3.3 V power supply input; bypassed internally by LDO - external 100 nF ceramic capacitor required at pin for high-frequency noise filtering.

Key Features

Feature	Design Value
DSPLL Any-Frequency Synthesis	Generates exact 156.25 MHz from fixed crystal - eliminates crystal procurement delays and enables single-BOM support across multiple designs.
On-Chip LDO Regulator	Provides >30 dB supply noise rejection up to 1 MHz - allows direct connection to noisy system rails without external regulators or ferrites.
Runt Suppression	Prevents sub-cycle pulses on CLK+/CLK− during OE transitions and power-on - avoids false clocking in sensitive receivers like SerDes PLLs.
Production-Tested Crystal ESR/DLD	Each unit undergoes individual crystal ESR and DLD screening - guarantees start-up reliability and long-term frequency stability over life.
Industry-Standard 5 × 7 mm Package	Compatible with automated SMT assembly and IPC-7351 land patterns - supports seamless integration into existing high-volume manufacturing lines.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
Si510BBA156M250AAG	Same frequency/stability/output but Si510 variant (CMOS, 4-pin, OE on pin 1); no differential outputs.	Limited to single-ended CMOS loads; unsuitable for LVDS receivers or high-noise environments requiring differential signaling.	Select only if board layout lacks space for 6-pin 5×7 mm or target IC accepts CMOS-level inputs.
AK2-156.250MHZ-EFE-T	156.25 MHz LVDS XO, ±25 ppm temp stability only (no 10-yr aging spec), 3.3 V, 5×7 mm, but analog PLL architecture.	Higher phase noise floor (>–115 dBc/Hz @10 kHz) and no integrated LDO - requires clean supply rail and external filtering.	Consider for cost-sensitive applications where 10-year aging is not required and supply noise is well-controlled.

Compared with Si510BBA156M250AAG and AK2-156.250MHZ-EFE-T, the 511SBA156M250BAG delivers superior long-term stability assurance, lower jitter via DSPLL, and built-in supply noise immunity - making it optimal for mission-critical infrastructure where timing integrity must be guaranteed over product lifetime.

FAQ

What output format and supply voltage does the 511SBA156M250BAG use?

The 511SBA156M250BAG is configured for LVDS output and 3.3 V supply, as indicated by the "SB" in its part number (S = 3.3 V, B = LVDS). It delivers differential 156.25 MHz signals with 100 Ω line-line termination, 0.35 V_PPSE typical swing, and operates across –40 °C to +85 °C without derating. This configuration is factory-programmed and non-field-adjustable.

Does the 511SBA156M250BAG support output enable control, and how is it implemented?

Yes, the 511SBA156M250BAG supports active-high output enable (OE) on pin 1, with an internal pull-up resistor (45 kΩ typical). When OE is high, CLK+/CLK− outputs are active; when low, outputs enter high-impedance state. Runt suppression prevents sub-cycle pulses during OE transitions, ensuring glitch-free operation critical for SerDes and FPGA transceivers.

What is the total frequency stability specification for the 511SBA156M250BAG, and what does it include?

The 511SBA156M250BAG has ±30 ppm total stability, which includes initial calibration accuracy, variation over –40 °C to +85 °C, supply voltage change (±10%), load change, mechanical shock/vibration (not under operation), and 10-year aging at 40 °C. This comprehensive spec eliminates need for field recalibration and supports long-lifecycle deployments in telecom and broadcast gear.

How does the DSPLL architecture in the 511SBA156M250BAG improve reliability compared to traditional XOs?

The 511SBA156M250BAG uses a fixed internal crystal with DSPLL synthesis instead of frequency-specific crystals. This eliminates crystal variability, improves mechanical robustness, and enables individual production testing of crystal ESR and DLD - guaranteeing start-up reliability and long-term stability. It also removes crystal aging uncertainty from the oscillator loop, enhancing 10-year timing predictability.

Can the 511SBA156M250BAG be used as a direct replacement for legacy LVDS oscillators in a 5 × 7 mm footprint?

Yes, the 511SBA156M250BAG uses the standard 5 × 7 mm, 6-pin CLCC package with pin-compatible layout to many legacy LVDS XOs. Its pin 1 (OE), pin 3 (GND), pin 4 (CLK+), pin 5 (CLK−), and pin 6 (VDD) match industry conventions. No PCB redesign is needed - only verify OE polarity and ensure 3.3 V supply meets ±10% tolerance and current capability (23 mA max).
