Product details

Overview

515CCA12M8000CAGR from Skyworks Solutions is a voltage-controlled crystal oscillator (VCXO) delivering 12.800 MHz output with ±20 ppm temperature stability, ±50 ppm absolute pull range, and 3.3 V CMOS output. It uses an integrated PLL-based synthesizer with a fixed AT-cut fundamental-mode crystal for high reliability and low aging. This device serves as the precision clock source in telecom line cards requiring stable frequency control under varying voltage and thermal conditions.

For engineers reviewing the 515CCA12M8000CAGR datasheet, 515CCA12M8000CAGR pinout, 515CCA12M8000CAGR application, or 515CCA12M8000CAGR equivalent, key selection criteria include its 12.8 MHz nominal frequency, CMOS output drive capability (±8 mA at 3.3 V), 1% control voltage linearity, 10 ms startup time, and 2.5×3.2 mm surface-mount package compatibility with industrial temperature range (–40 to +85 °C).

Technical Context

The 515CCA12M8000CAGR implements Skyworks' proprietary PLL-based frequency synthesis architecture, enabling any frequency from 100 kHz to 212.5 MHz (CMOS variant limit) using a single fixed-frequency crystal resonator. Its control voltage input (Vc) accepts 0.1×VDD to 0.9×VDD with selectable Kv of ±90 ppm/V (per second option code 'C'), and features internal OE polarity configuration with pull-up resistor.

It integrates power supply filtering and ADC-based tuning path for high PSRR (>4 ps additive jitter at 100–500 kHz noise), supports tristate operation with <22 mA disable current, and achieves 0.25–0.35 ps RMS phase jitter (1.875 MHz–20 MHz integration) in CMOS mode - critical for low-jitter PLL reference applications in PON and xDSL systems.

Key Specifications

Parameter	Value and Actual Design Meaning
Nominal Frequency	12.800 MHz - factory-programmed exact output; enables precise timing alignment in SONET/SDH framers and Ethernet PHYs.
Output Format	CMOS - single-ended, rail-to-rail swing (0.15×VDD low / 0.85×VDD high), 0.6–1.2 ns rise/fall time, suitable for FPGA clock inputs and ASIC reset synchronization.
Supply Voltage	3.3 V ±10% - standard logic rail; draws 24–29 mA typical at 100 MHz (scaled lower at 12.8 MHz), compatible with common LDO-regulated power domains.
Tuning Slope (Kv)	±90 ppm/V - linear control sensitivity over 0.33–2.97 V range; enables predictable frequency adjustment in closed-loop clock recovery circuits.
Temperature Stability	±20 ppm over –40 to +85 °C - ensures frequency deviation remains within 256 Hz at 12.8 MHz across full industrial operating range.
Aging	±8.5 ppm over 10 years - guarantees long-term accuracy without field recalibration in deployed telecom infrastructure equipment.
Startup Time	≤10 ms - meets fast-boot requirements in carrier-grade switches and optical line terminals needing rapid clock availability after power-on.

Pinout & Package

515CCA12M8000CAGR is housed in a RoHS-compliant, lead-free 2.5 × 3.2 mm 6-pin surface-mount package (package code 'C' per ordering guide). The footprint conforms to JEDEC MO-220 and IPC-7351 standards, with 1.25 mm pitch and NSMD land pattern (C1 = 1.9 mm, X1 = 0.70 mm, Y1 = 1.05 mm).

Pin/Terminal	Circuit Role	Design Meaning
1	Vc	Control voltage input; accepts analog tuning signal (0.33–2.97 V); 100 kΩ input impedance minimizes loading on external DAC or loop filter.
2	OE	Output enable; active-high with internal 45 kΩ pull-up; asserts tristate when low, reducing system power during idle states.
3	GND	Electrical and case ground; must be connected to low-impedance PCB ground plane to maintain jitter performance and EMI integrity.
4	CLK	CMOS clock output; 3.3 V rail-to-rail swing; drives up to 15 pF load with sub-nanosecond edge rates; no termination required.
5	NC	No connect; left unconnected per datasheet; floating pin must not be tied to VDD, GND, or other signals to avoid parasitic coupling.
6	VDD	3.3 V power supply; requires local 100 nF ceramic decoupling adjacent to pin; sensitive to supply ripple due to PLL sensitivity.

Key Features

Feature	Design Value
Any-frequency synthesis	12.800 MHz generated via on-chip PLL from fixed crystal - eliminates custom crystal procurement and reduces BOM complexity.
High power supply noise rejection	≤4.0 ps added jitter under 100 mVPP 100–500 kHz supply noise - enables direct use in noisy digital power domains without dedicated LDO.
1% control voltage linearity	BSL error ≤±1% across 10–90% VDD range - ensures monotonic, predictable tuning response in analog control loops.
Short lead times	Factory-configured and shipped in <2 weeks - avoids 12–16 week custom oscillator wait times for legacy VCXOs.
AT-cut fundamental crystal	Low aging (±8.5 ppm/10 yr) and high mechanical robustness - improves MTBF in vibration-prone telecom chassis and outdoor cabinets.

Equivalent & Alternatives

The following parts are listed as comparable options for similar VCXO applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
Si514ACA12M8000CGR	Same Si515 family but Si514 variant; lacks integrated PLL - limited to crystal's fundamental frequency only (no any-frequency synthesis).	Only supports fixed 12.8 MHz; cannot be reprogrammed for other frequencies; no Kv or APR flexibility.	Select only if cost-sensitive, fixed-frequency-only requirement exists and future frequency changes are ruled out.
DS3205Z-12.8M	Discrete VCXO with separate crystal + varactor; ±25 ppm stability; 3.3 V CMOS; 15 ppm/V tuning slope; 15 ms startup.	Higher aging (±15 ppm/10 yr); no factory programming; requires external loop filter components.	Choose when legacy discrete design reuse is mandatory or when ultra-low-cost, non-programmable solution suffices.

Compared with Si514ACA12M8000CGR and DS3205Z-12.8M, the 515CCA12M8000CAGR delivers programmable frequency synthesis, superior aging, faster startup, and integrated tuning linearity - making it optimal for next-gen programmable timing in telecom and broadcast platforms.
