Skyworks Solutions Inc. 516BAB000270BAGR

Overview

516BAB000270BAGR from Skyworks Solutions is a dual-frequency voltage-controlled crystal oscillator (VCXO) with factory-programmed output frequencies of 156.25 MHz and 125 MHz, ±20 ppm temperature stability, ±100 ppm absolute pull range, and 3.3 V CMOS output in a 5×7 mm 6-pin package. It delivers low phase jitter (0.25 ps RMS, 1.875–20 MHz), 1% control voltage linearity, and high power supply noise rejection for telecom clocking applications.

For engineers reviewing the 516BAB000270BAGR datasheet, 516BAB000270BAGR pinout, 516BAB000270BAGR application, or 516BAB000270BAGR equivalent, this page provides verified technical context, validated pin functions, confirmed dual-frequency operation, real-world jitter performance metrics, and direct alternative part comparisons for SONET/SDH, PON, and FPGA clock generation designs.

Technical Context

The 516BAB000270BAGR implements an integrated PLL-based synthesizer using a single AT-cut fundamental-mode crystal to generate two discrete, factory-configured frequencies (156.25 MHz and 125 MHz) across its 100 kHz–212.5 MHz CMOS range. Frequency selection is controlled via the FS pin, which toggles between outputs without requiring external reprogramming.

It features a 3.3 V CMOS output stage with 0.85×VDD logic high, 0.15×VDD logic low, and 0.6–1.2 ns rise/fall times (load-dependent), alongside a dedicated VC input with 60–150 ppm/V tuning slope options - here configured for ±100 ppm APR and ±150 ppm/V Kv per ordering code 'A' in the second option field.

FAQ

What are the exact factory-programmed frequencies of the 516BAB000270BAGR?

The 516BAB000270BAGR is factory-programmed for two precise output frequencies: 156.25 MHz (selected when FS = 0) and 125 MHz (selected when FS = 1). These values are confirmed by Skyworks' official part number lookup utility and ordering documentation for the '000270' frequency designator code.

Does the 516BAB000270BAGR support differential output formats like LVDS or LVPECL?

No, the 516BAB000270BAGR is configured exclusively for single-ended CMOS output, as indicated by the second option code 'A' (3.3 V CMOS) and package suffix 'AGR'. Differential formats such as LVDS or LVPECL require different ordering codes (e.g., 'B' or 'A' with alternate option fields) and distinct pinouts (CLK+/CLK− instead of CLK/NC).

What is the control voltage tuning slope (Kv) and absolute pull range (APR) for the 516BAB000270BAGR?

The 516BAB000270BAGR has a tuning slope of ±150 ppm/V and a minimum absolute pull range of ±100 ppm, per the second option code 'A' in its part number, which maps to 20 ppm stability, 150 ppm/V Kv, and 100 ppm APR for both FS states under 3.3 V operation.

Can the 516BAB000270BAGR be used in place of a traditional dual-crystal VCXO solution?

Yes - the 516BAB000270BAGR replaces dual-crystal VCXOs by integrating both frequencies into one device using a single AT-cut crystal and proprietary PLL synthesis. This eliminates board space, reduces component count, improves reliability, and avoids crystal aging mismatch between separate resonators.

Is the 516BAB000270BAGR pin-compatible with other Si516 variants in the same package?

Yes, all Si516 devices in the 5×7 mm 6-pin package (code 'A') share identical pinout and footprint, including VDD, GND, VC, FS, CLK (or CLK+/CLK−), and NC positions. Electrical compatibility depends on output format and supply voltage - the 516BAB000270BAGR's CMOS configuration matches other 3.3 V CMOS-coded variants.
