Skyworks Solutions Inc. 516BKB000132BAGR

Overview

516BKB000132BAGR 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, 120 ppm/V tuning slope, and 5 × 7 mm 6-pin package. It supports CMOS output format, 3.3 V supply, and operates across –40 °C to +85 °C for telecom clocking and FPGA synchronization.

For engineers reviewing the 516BKB000132BAGR datasheet, 516BKB000132BAGR pinout, 516BKB000132BAGR application, or 516BKB000132BAGR equivalent, this page delivers verified electrical specs, dual-frequency switching behavior, control voltage linearity (±1% BSL), jitter performance (0.25–0.35 ps RMS phase jitter), and package-specific layout guidance for production-grade timing design.

Technical Context

The 516BKB000132BAGR implements an integrated PLL-based synthesizer using a fixed AT-cut fundamental-mode crystal, enabling two user-selectable frequencies without discrete crystal swaps. Its digital frequency selection (FS pin) toggles between 156.25 MHz and 125 MHz with ≤10 ms settling time.

It features 120 ppm/V Kv tuning slope, 1% control voltage linearity (BSL), and high power supply noise rejection-demonstrated by ≤4.0 ps additive jitter under 100 kHz VDD sinusoidal noise-making it suitable for low-jitter PLLs in noisy telecom and broadcast environments.

FAQ

What are the two factory-programmed output frequencies of the 516BKB000132BAGR?

The 516BKB000132BAGR is factory-configured for 156.25 MHz and 125 MHz outputs. These frequencies are selected via the FS pin: logic low chooses 156.25 MHz, and logic high selects 125 MHz. Both frequencies are guaranteed across –40 °C to +85 °C with ±20 ppm stability and supported by the device's 120 ppm/V tuning slope.

Does the 516BKB000132BAGR support CMOS output with 3.3 V supply?

Yes, the 516BKB000132BAGR is configured for CMOS output and 3.3 V operation (option code "B" in the 1st option field). It delivers rail-to-rail logic levels (VOH ≥ 0.85×VDD, VOL ≤ 0.15×VDD), 0.6–1.2 ns rise/fall times, and 24–29 mA typical supply current-fully compliant with standard 3.3 V CMOS interface requirements.

What is the control voltage range and linearity specification for the 516BKB000132BAGR?

The 516BKB000132BAGR accepts a control voltage (V_C) from 0.1×V_DD to 0.9×V_DD (0.33–2.97 V at 3.3 V supply) with ±1% baseline linearity (BSL). This ensures predictable frequency pull across the full tuning range, critical for closed-loop clock recovery and jitter attenuation applications.

How does the 516BKB000132BAGR achieve low phase jitter despite using an integrated PLL?

The 516BKB000132BAGR achieves 0.25 ps RMS phase jitter (1.875–20 MHz) through Skyworks' proprietary PLL architecture, AT-cut fundamental crystal stability, and optimized charge-pump design. Its high PSRR (≤4.0 ps added jitter under 100 kHz VDD noise) and 1% V_C linearity further suppress jitter sources inherent in integrated synthesizers.

Is the 516BKB000132BAGR pin-compatible with other Si516 variants in the 5 × 7 mm package?

Yes, all Si516 devices in the 5 × 7 mm 6-pin package-including 516BKB000132BAGR-share identical pinout (V_C, FS, GND, CLK, NC, V_DD for CMOS variants) and mechanical footprint. This allows drop-in replacement across configurations differing only in frequency, output format, or tuning slope-provided the FS logic polarity and V_C range match system requirements.
