Product details
Overview
512BAA000270BAGR from Skyworks Solutions is a dual-frequency, factory-programmed crystal oscillator (XO) with CMOS output, 3.3 V supply, ±30 ppm total stability, and 3.2×5 mm SMD package. It delivers two user-selectable frequencies-27 MHz and 70 MHz-via the FS pin, supporting telecom and datacom clocking in FPGA/ASIC timing and Gigabit Ethernet PHY interfaces.
For engineers reviewing the 512BAA000270BAGR datasheet, 512BAA000270BAGR pinout, 512BAA000270BAGR application, or 512BAA000270BAGR equivalent, key selection criteria include dual-frequency switching latency (<10 ms settling), OE polarity configuration, CMOS drive strength (±8 mA at 3.3 V), and compatibility with industrial temperature range (–40 to +85 °C) and RoHS-compliant 3.2×5 mm footprint.
Technical Context
The 512BAA000270BAGR implements Skyworks' DSPLL® synthesis architecture with a fixed internal crystal and programmable fractional-N PLL, enabling precise frequency generation across 100 kHz–212.5 MHz without external components. Its dual-frequency operation is controlled by a single digital FS input, selecting between two factory-programmed frequencies.
It integrates an on-chip LDO regulator for supply noise rejection, supports active-high OE with internal pull-up, and features runt suppression on both OE and power-on transitions. The device uses a 6-pin CMOS pinout (OE on pin 2, FS on pin 1) and operates exclusively in CMOS mode-no LVDS/LVPECL/HCSL variants.

Use Value: Ensures phase-coherent timing between layers, improving BER margin and reducing jitter accumulation across the physical layer stack. |
| FPGA Configuration & I/O Clocking | Broadcast Video Processing |
Use Scenario: High-speed FPGA-based test equipment with multiple clock domains-one for configuration logic, another for high-speed serial I/O transceivers. IC Role / Device Role / Timing Role: Delivers 27 MHz to FPGA configuration interface (JTAG, SPI) and 70 MHz to GTY/GTP transceivers as reference for 5.6 Gbps lanes. Use Value: Enables deterministic startup and lock timing; avoids need for separate oscillators with independent aging drift and supply sensitivity. | Use Scenario: SDI video encoders/decoders supporting both 27 MHz SMPTE 259M (HD-SDI) and 74.25 MHz SMPTE 424M (3G-SDI) standards in a single hardware platform. IC Role / Device Role / Timing Role: Generates 27 MHz for legacy HD-SDI processing and 70 MHz (close approximation to 74.25 MHz, within system tolerance) for 3G-SDI pixel clocking. Use Value: Allows field-upgradable video format support via software-controlled FS pin-no hardware change required. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-frequency oscillator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Si512BAA000270BAGM | Same Si512 family, identical frequencies and stability, but shipped in cut tape (not tape-and-reel); no functional difference | Identical use cases; only differs in packaging format for low-volume prototyping vs. production | Select 512BAA000270BAGR for automated SMT assembly; choose BAGM for hand-soldered evaluation or small-batch builds |
| Si53204-A01770-GM | Multi-output clock generator (4 outputs), not dual-frequency XO; requires external configuration EEPROM and I²C setup | Supports more complex clock trees but adds firmware dependency, layout complexity, and higher BOM cost | Choose only if ≥3 synchronized outputs or programmable frequency agility beyond two fixed points is required |
Compared with Si512BAA000270BAGM, 512BAA000270BAGR offers identical electrical performance with optimized logistics for volume manufacturing; compared with Si53204-A01770-GM, it provides simpler, lower-risk timing with zero configuration overhead-but lacks multi-output flexibility.

FAQ
What are the exact factory-programmed frequencies for 512BAA000270BAGR?
The 512BAA000270BAGR is programmed with two precise frequencies: 27.000 MHz (selected when FS = 0) and 70.000 MHz (selected when FS = 1). These values are permanently stored in the device's non-volatile memory at Skyworks' factory and cannot be altered in the field. Both frequencies meet ±30 ppm total stability over –40 to +85 °C, as verified per Table 2 in the Si512/513 datasheet Rev. 1.2.
Does 512BAA000270BAGR support LVDS or LVPECL output formats?
No, 512BAA000270BAGR is a CMOS-output-only variant. Its part number prefix "512" and suffix "BAGR" indicate Si512 series, CMOS output, OE on pin 2, 3.2×5 mm package, and tape-and-reel shipping. LVDS/LVPECL/HCSL versions use different output codes (e.g., "E" for 2.5 V LVPECL) and distinct pinouts with differential CLK+/CLK– pairs. Attempting to drive LVDS loads with 512BAA000270BAGR will result in incorrect logic levels and potential signal integrity issues.
What is the function of Pin 5 (NC) on 512BAA000270BAGR, and can it be grounded?
Pin 5 on 512BAA000270BAGR is designated NC (No Connect) and is internally unconnected. It must remain electrically floating-neither grounded nor tied to VDD or any other signal. Connecting Pin 5 may cause unpredictable behavior, increased current draw, or failure to meet jitter specifications. The Si512/513 datasheet explicitly states "Make no external connection to this pin" in Table 11, and Skyworks validates performance only under this condition.
How does the OE (Output Enable) pin behave during power-up, and is external pull-up required?
The OE pin on 512BAA000270BAGR has an internal 45 kΩ pull-up resistor, so it defaults to logic high at power-up-enabling the CLK output automatically once VDD stabilizes and startup time (≤10 ms) elapses. No external pull-up is needed. When OE is driven low, the CLK pin enters high-impedance state with ≤18 mA tristate current (Table 1). Runt suppression ensures no spurious edges occur during OE transitions.
Can 512BAA000270BAGR be used in automotive applications requiring AEC-Q200 qualification?
No, 512BAA000270BAGR is specified for industrial temperature range (–40 to +85 °C) and is not AEC-Q200 qualified. It lacks automotive-grade screening, extended temperature validation (–40 to +105 °C or +125 °C), and stress testing per AEC-Q200 requirements. For automotive timing, Skyworks offers the Si54x family (e.g., Si549A-D-GM), which is AEC-Q200 qualified and supports similar dual-frequency functionality-but with different pinout, package, and ordering codes.
