Skyworks Solutions Inc. 516CAA000109AAG

Overview

516CAA000109AAG from Skyworks Solutions is a dual-frequency voltage-controlled crystal oscillator (VCXO) supporting 100 kHz to 250 MHz output range with factory-programmed frequencies of 156.25 MHz and 125 MHz, ±20 ppm temperature stability, ±150 ppm/V tuning slope, and 3.3 V CMOS output in a 5×7 mm 6-pin package. It serves as a low-jitter, high-reliability clock source for telecom synchronization and FPGA timing.

For engineers reviewing the 516CAA000109AAG datasheet, 516CAA000109AAG pinout, 516CAA000109AAG application, or 516CAA000109AAG equivalent, this page delivers verified specifications, validated pin functions, confirmed dual-frequency switching behavior via FS control, and real-world jitter performance (0.25–0.35 ps RMS phase jitter, 1.875–20 MHz integration) for SONET/SDH and PON system design.

Technical Context

The 516CAA000109AAG implements an integrated PLL-based synthesizer using a fixed AT-cut fundamental-mode crystal, eliminating need for multiple crystals while delivering two user-selectable frequencies. Its architecture enables superior supply noise rejection (≤4.0 ps additive jitter at 100–500 kHz VDD noise) and 1% control voltage linearity across 0.1×VDD to 0.9×VDD.

Frequency selection is performed via the FS pin (0 = 156.25 MHz, 1 = 125 MHz), with tristate capability and <10 ms settling time after FS transition. The device operates over –40°C to +85°C and supports CMOS logic levels with 0.85×VDD VOH and 0.15×VDD VOL thresholds.

FAQ

What are the two factory-programmed output frequencies of the 516CAA000109AAG?

The 516CAA000109AAG is factory-programmed for 156.25 MHz (selected when FS = 0) and 125 MHz (selected when FS = 1). These frequencies align with IEEE 802.3ae 10GBASE-R Ethernet and GPON standards respectively, and are permanently stored in the device's non-volatile memory at time of shipment.

Does the 516CAA000109AAG require external configuration or programming after soldering?

No, the 516CAA000109AAG is fully factory-configured before shipment. All parameters-including frequencies, output format (CMOS), supply voltage (3.3 V), temperature stability (±20 ppm), and tuning slope (±150 ppm/V)-are programmed into the device and require no post-soldering configuration or I²C/SPI interface.

What is the maximum allowable control voltage range for the Vc pin on the 516CAA000109AAG?

The Vc pin on the 516CAA000109AAG accepts a control voltage from 0.1×VDD to 0.9×VDD, i.e., 0.33 V to 2.97 V for a 3.3 V supply. Operation outside this range may cause frequency instability or exceed absolute maximum ratings specified in Table 11 of the datasheet.

Can the 516CAA000109AAG operate with a 2.5 V supply instead of 3.3 V?

No, the 516CAA000109AAG is configured for 3.3 V operation only, as indicated by the first option code "A" in its part number. Using 2.5 V will result in insufficient VOH/VOL levels, degraded jitter performance, and potential failure to meet output drive specifications per Table 4.

What is the typical phase jitter performance of the 516CAA000109AAG at 156.25 MHz?

At 156.25 MHz, the 516CAA000109AAG delivers 0.25 ps RMS phase jitter (1.875–20 MHz integration bandwidth) and 0.8 ps RMS (12 kHz–20 MHz), meeting OC-192 and 10GBASE-R timing requirements. This value is measured under standard conditions (VDD = 3.3 V, TA = 25°C) and confirmed in Table 8 of the official datasheet.
