Product details

Overview

VC-830-ECE-KAAN-156M250000TR from Microchip Technology is a hermetically sealed, LVPECL-output crystal oscillator delivering 156.25 MHz at 3.3 V, with ±50 ppm frequency stability over –40°C to +105°C, 40 fsRMS phase jitter (12 kHz–20 MHz), and differential output for low-noise clocking in high-speed serial interfaces.

For engineers reviewing the VC-830-ECE-KAAN-156M250000TR datasheet, VC-830-ECE-KAAN-156M250000TR pinout, VC-830-ECE-KAAN-156M250000TR application, or VC-830-ECE-KAAN-156M250000TR equivalent, this page provides verified electrical specs, package dimensions, enable/disable behavior, jitter performance at 156.25 MHz, and real-world deployment guidance for SynchE, Fibre Channel, and FPGA timing systems.

Technical Context

The VC-830-ECE-KAAN-156M250000TR implements a quartz-stabilized oscillator core with LVPECL differential outputs, supporting glitch-free startup and enable control via Pin 1 (E/D). It uses a fundamental or 3rd-overtone crystal design optimized for 100–200 MHz operation.

Its electrical architecture includes internal oscillation detection, 50Ω load-optimized rise/fall times ≤400 ps, and PSRR enhancement to suppress supply noise-critical for maintaining sub-50 fs jitter in Ethernet and storage applications where power rail integrity varies.

Key Specifications

Parameter	Value and Actual Design Meaning
Nominal Frequency	156.25 MHz - precisely matches IEEE 1588 PTP, SyncE, and 10GbE reference clock requirements.
Output Logic	LVPECL - delivers fast edge rates (≤400 ps) and robust noise immunity for point-to-point high-speed interconnects.
Frequency Stability	±50 ppm - covers full operating range (–40°C to +105°C), aging, voltage variation, and reflow effects per spec.
Phase Jitter (12 kHz–20 MHz)	40 fsRMS typical - meets stringent jitter budgets for 10G/25G SerDes and ADC sampling clocks.
Supply Voltage	3.3 V ±5% - compatible with standard logic rails; requires 10 µF / 0.1 µF / 0.01 µF decoupling per datasheet.
Operating Temperature	–40°C to +105°C - qualified for industrial and telecom infrastructure environments without derating.
Package	6-pin 3.2 mm × 2.5 mm VDFN - surface-mount ceramic package with gold-over-nickel terminations and MSL 1 rating.

Pinout & Package

Hermetically sealed 3.2 mm × 2.5 mm VDFN package with 6 terminals, gold-over-nickel contact pads (0.3–1.0 µm), θJC = 28°C/W, and moisture sensitivity level (MSL) 1.

Pin/Terminal	Circuit Role	Design Meaning
1 (E/D)	Enable/Disable control input	Logic-high or open = outputs enabled; logic-low = high-impedance state; internal pull-up ensures safe default-on behavior.
2 (NC)	No internal connection	Unbonded pad; must remain unconnected on PCB to avoid parasitic coupling or mechanical stress.
3 (GND)	Electrical and lid ground	Common return for oscillator core, output drivers, and E/D logic; requires low-inductance connection to system ground plane.
4 (fO)	Differential output (non-inverted)	LVPECL output referenced to VDD − 0.88 V (min) at 3.3 V; requires 50Ω termination to VDD − 2.0 V for proper common-mode level.
5 (CfO)	Differential output (inverted)	Complementary LVPECL output; must be terminated identically to fO to prevent jitter degradation and signal integrity loss.
6 (VDD)	Power supply input	3.3 V ±5% supply; decoupling network (10 µF / 0.1 µF / 0.01 µF) mandatory per datasheet to maintain 40 fsRMS jitter performance.

Key Features

Feature	Design Value
40 fsRMS phase jitter (12 kHz–20 MHz)	Enables compliance with OC-192, 10GBASE-R, and CPRI timing masks without external jitter cleaning.

Excellent PSRR	Minimizes supply-induced jitter; allows direct use with switching regulators in space-constrained telecom modules.
RoHS-compliant & lead-free assembly compatible	Supports IPC/JEDEC J-STD-020D MSL 1 reflow profile up to 260°C peak, enabling high-yield SMT manufacturing.

FAQ

What is the exact output logic standard and voltage compliance of VC-830-ECE-KAAN-156M250000TR?

The VC-830-ECE-KAAN-156M250000TR features LVPECL output compliant with JEDEC JESD8-12 standards. At 3.3 V supply, VOH is VDD − 0.880 V (min) and VOL is VDD − 1.620 V (max), with 50Ω termination to VDD − 2.0 V. This ensures interoperability with TI, Renesas, and Broadcom SerDes receivers requiring true LVPECL signaling levels without level translation.

Does VC-830-ECE-KAAN-156M250000TR require external termination resistors, and if so, what values are recommended?

Yes, VC-830-ECE-KAAN-156M250000TR requires matched 50Ω terminations on both fO and CfO outputs to VDD − 2.0 V for LVPECL operation. Figure 3-1 in the datasheet specifies 50Ω pull-down for 3.3 V supply. Unequal or missing termination causes excessive jitter and duty cycle distortion-verified by Microchip's application testing at 156.25 MHz.

What is the start-up time and enable/disable behavior of VC-830-ECE-KAAN-156M250000TR?

The VC-830-ECE-KAAN-156M250000TR has a maximum start-up time of 10 ms after VDD reaches regulation. The E/D pin (Pin 1) enables outputs when driven high or left open (internal pull-up); pulling low places outputs in high-impedance state within 200 ns. Oscillation detection guarantees glitch-free transitions-critical for FPGA configuration and hot-swap systems.

Is VC-830-ECE-KAAN-156M250000TR qualified for lead-free reflow, and what is its moisture sensitivity level?

Yes, VC-830-ECE-KAAN-156M250000TR is qualified for standard lead-free IR reflow per J-STD-020D, with peak temperature up to 260°C for 30 seconds. Its moisture sensitivity level is MSL 1-meaning unlimited floor life at ≤30°C/60% RH, eliminating bake requirements before assembly and supporting high-throughput SMT lines.

How does the phase noise profile of VC-830-ECE-KAAN-156M250000TR support 10GBASE-R and CPRI applications?

At 156.25 MHz, VC-830-ECE-KAAN-156M250000TR achieves –160 dBc/Hz at 100 kHz offset and –167 dBc/Hz at 20 MHz offset. Integrated phase jitter (12 kHz–20 MHz) is 40 fsRMS-well below the 100 fs RMS limit for 10GBASE-R and CPRI Option 3, ensuring clean eye diagrams and low BER in optical transport systems.
