Product details
Overview
513BAA000644BAGR from Skyworks Solutions is a dual-frequency crystal oscillator (XO) with factory-programmed frequencies of 100 MHz and 125 MHz, operating at 3.3 V with ±30 ppm total stability over –40 to +85 °C. It uses DSPLL® synthesis on a fixed crystal, supports LVPECL/LVDS/HCSL/CMOS outputs, and delivers low jitter (1.3 ps RMS period jitter for LVPECL). It serves as a precision clock source in PCIe Gen3/Gen4 root complexes and FPGA-based telecom line cards.
For engineers reviewing the 513BAA000644BAGR datasheet, 513BAA000644BAGR pinout, 513BAA000644BAGR application, or 513BAA000644BAGR equivalent, key selection criteria include dual-frequency switching via FS pin, OE polarity configuration, supply noise rejection performance, and compatibility with 3.2×5 mm 6-pin surface-mount footprint.
Technical Context
The 513BAA000644BAGR implements Skyworks' DSPLL® architecture with a fixed internal crystal and fractional-N synthesizer, enabling any-frequency generation from 100 kHz to 250 MHz without external crystals. Its dual-output capability is realized through a single PLL core with frequency-select logic routed to CLK+/CLK– or CMOS CLK pins depending on output format.
It integrates an on-chip LDO regulator for supply noise filtering, supports runt suppression on OE and power-on reset, and includes internal pull-up/pull-down resistors (45 kΩ) on FS and OE pins. The device is factory-configured - no field programming - with frequencies, voltage, output format, and stability permanently programmed before shipment.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Nominal Frequencies | 100 MHz and 125 MHz - factory-programmed dual outputs selectable via FS pin; enables dynamic clock domain switching without external multiplexers. |
| Output Format | LVPECL/LVDS/HCSL/CMOS - supports high-speed serial interfaces including PCIe, SATA, and Fibre Channel with signal integrity-optimized drive strength. |
| Total Stability | ±30 ppm - includes initial accuracy, temperature variation (–40 to +85 °C), supply/load changes, shock/vibration, and 10-year aging at 40 °C. |
| Supply Voltage | 3.3 V ±10% - compatible with standard logic rails; internal LDO ensures stable core operation despite board-level supply ripple. |
| Period Jitter (RMS) | 1.3 ps (LVPECL) - meets PCIe Gen3/Gen4 reference clock jitter requirements (<1.5 ps RMS) for reliable high-speed link training. |
| Startup Time | ≤10 ms - time from minimum VDD to output within frequency tolerance; enables fast system boot and hot-plug readiness. |

Pinout & Package
513BAA000644BAGR is supplied in a 3.2 × 5.0 mm, 6-pin surface-mount package (package code B). Pin 1 = OE, Pin 2 = FS, Pin 3 = GND, Pin 4 = CLK+, Pin 5 = CLK–, Pin 6 = VDD.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OE) | Output Enable | Active-high control input with internal 45 kΩ pull-up; disables both outputs when low, reducing system power during idle states. |
| 2 (FS) | Frequency Select | Digital select input (0 = 100 MHz, 1 = 125 MHz); supports real-time clock domain switching without interrupting system operation. |
| 3 (GND) | Ground Reference | Common electrical and case ground; must be connected to low-impedance PCB ground plane to minimize jitter and EMI. |
| 4 (CLK+) | Differential Clock Output | Non-inverted LVPECL/LVDS/HCSL output; requires 50 Ω termination to VDD – 2 V (LVPECL) or 100 Ω differential (LVDS). |
| 5 (CLK–) | Differential Clock Output | Inverted complement of CLK+; used with CLK+ to deliver low-skew, noise-rejecting differential signaling. |
| 6 (VDD) | Power Supply | 3.3 V ±10% input; powers internal LDO, PLL, and output drivers; bypass capacitor (0.1 µF) required adjacent to pin. |
Key Features
| Feature | Design Value |
|---|---|
| Dual-frequency DSPLL® synthesis | Enables two precise, factory-set frequencies (100/125 MHz) from one device - eliminates need for dual discrete XOs and reduces BOM count and board area. |
| On-chip LDO regulator | Provides >30 dB supply noise rejection up to 1 MHz, allowing direct connection to noisy system rails without external filtering components. |
| Runt suppression on OE and power-on | Prevents false clock edges during enable transitions or brown-out conditions - critical for deterministic FPGA configuration and SerDes lock acquisition. |
| Factory-programmed configuration | Delivers fully functional, tested device with zero NRE or lead time for custom frequencies - accelerates design-in and production ramp. |
| Industry-standard 3.2×5 mm package | Ensures drop-in compatibility with existing layout footprints and pick-and-place tooling across telecom, computing, and industrial platforms. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-frequency oscillator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Si512BAA000644BAGR | OE pin on Pin 2 (vs. Pin 1 on 513BAA000644BAGR); identical frequencies, stability, and package. | Requires PCB layout revision to swap OE/FS pin assignments; not pin-compatible. | Select only if redesigning board layout to match Si512's OE-on-Pin-2 convention. |
| Si542A-A02579-GM | Single-output, 125 MHz only; ultra-low jitter (0.17 ps RMS); 2.5 V supply; 2.0 × 2.5 mm package. | Lacks dual-frequency capability and FS control; smaller footprint but no frequency switching. | Choose when only one frequency is needed and jitter budget is tighter than 513BAA000644BAGR's 1.3 ps RMS. |
Compared with Si512BAA000644BAGR, 513BAA000644BAGR offers native OE-on-Pin-1 layout compatibility for new designs, while Si542A-A02579-GM trades dual-frequency flexibility for superior jitter performance and space savings where single-frequency operation suffices.

FAQ
What are the factory-programmed frequencies of the 513BAA000644BAGR?
The 513BAA000644BAGR is factory-programmed with two precise output frequencies: 100 MHz and 125 MHz. These values are permanently stored in non-volatile memory and cannot be altered in the field. Frequency selection is controlled by the logic level applied to the FS pin (Pin 2): FS = 0 selects 100 MHz, FS = 1 selects 125 MHz. Both frequencies are delivered simultaneously on complementary differential outputs (CLK+/CLK–) when enabled.
Is the 513BAA000644BAGR pin-compatible with other Si512/513 variants?
No - the 513BAA000644BAGR has OE on Pin 1 and FS on Pin 2, which differs from Si512-series devices (OE on Pin 2, FS on Pin 1). While both share the same 3.2×5 mm 6-pin package outline and pin numbering, swapping them requires PCB layout modification. The 513BAA000644BAGR is pin-compatible only with other Si513-part-numbered devices sharing the same package code (B) and output format configuration.
What output formats does the 513BAA000644BAGR support?
The 513BAA000644BAGR supports LVPECL, LVDS, HCSL, and CMOS output formats - selected at factory configuration. As indicated by its part number suffix "BAA", this unit is configured for LVPECL/LVDS/HCSL/Dual CMOS operation (not CMOS-only), meaning it delivers differential outputs on Pins 4 (CLK+) and 5 (CLK–). CMOS-only variants use different pinouts (CLK on Pin 4, NC on Pin 5) and are designated with "C" or "K" in the output format code.
Does the 513BAA000644BAGR require external configuration or programming after soldering?
No - the 513BAA000644BAGR is fully factory-programmed prior to shipment. All parameters - including frequencies (100/125 MHz), output format (LVPECL/LVDS/HCSL), supply voltage (3.3 V), total stability (±30 ppm), OE polarity, and FS functionality - are permanently written into the device. No I²C, SPI, or other interface is present; operation begins immediately upon power-up with no initialization sequence required.
How does the on-chip LDO in the 513BAA000644BAGR improve system-level jitter performance?
The integrated LDO regulator in the 513BAA000644BAGR provides >30 dB supply noise rejection up to 1 MHz, effectively isolating the sensitive PLL core from board-level power rail noise. This allows the 513BAA000644BAGR to maintain 1.3 ps RMS period jitter even when powered directly from a noisy 3.3 V system rail - eliminating the need for external LDOs, ferrite beads, or complex decoupling networks typically required for discrete oscillators.
