Microchip TimeProvider® 4100

Reliable PTP Grandmaster for 5G, Utilities and Critical Infrastructure

Modern networks are more dependent on precise timing than ever before. Whether in 5G mobile networks, power utilities, industrial systems, or transportation infrastructure, accurate time synchronization is essential for performance, stability, and security.Microchip TimeProvider® 4100, supplied and supported by Amtest‑TM, is a proven solution for customers who require:

nanosecond-level accuracy
resilience against GNSS outages
scalable and secure timing architecture
seamless integration of modern and legacy technologies

Why choose TimeProvider 4100

TimeProvider 4100 is more than just a PTP Grandmaster - it is a complete timing platform that integrates multiple synchronization technologies into a single system:

PTP Grandmaster (IEEE 1588 v2)
Synchronous Ethernet (SyncE)
GNSS (multi-constellation, multi-band)
NTP server
Legacy timing (E1/T1, 1PPS, 10 MHz)

This means one platform for your entire timing infrastructure, reducing complexity and operational costs.

Ready for 5G and next-generation networks

With the rollout of 5G, timing requirements have become significantly more demanding:

phase synchronization
real-time accuracy
resilience to packet network impairments

TimeProvider 4100 fully supports:

ITU-T G.8275.1 / G.8275.2 (5G timing profiles)
SyncE for frequency distribution
Boundary Clock Class C and D (<10 ns / <5 ns)

Ideal for:

fronthaul, midhaul, and backhaul
C-RAN and O-RAN architectures
core and aggregation sites

High accuracy and performance

The platform meets the most stringent timing standards:

PRTC Class A: 100 ns
PRTC Class B: 40 ns
ePRTC: up to 30 ns

This makes it suitable for:

telecom networks
power utilities (IEC 61850)
financial systems
metrology and laboratories
critical infrastructure

GNSS resilience and holdover performance

GNSS signals are not always reliable. TimeProvider 4100 ensures continuous operation even during outages.

Advanced holdover options

Available oscillator types:

OCXO
Super OCXO
Rubidium (recommended for critical applications)

Rubidium provides:

superior long-term stability
minimal drift
reliable operation without GNSS

ePRTC capability

autonomous time source
independence from GNSS
support for integration with atomic clocks

Protection against interference and cyber threats

TimeProvider 4100 addresses modern security challenges:

GNSS protection (BlueSky technology)

detection of jamming and spoofing
continuous signal monitoring
automated mitigation actions

Network security

RADIUS / TACACS+ / 2FA
X.509 certificates
ACL and firewall
IEEE 1588-2019 security features

Suitable for high-security environments.

High availability and redundancy

Designed for mission-critical applications, TimeProvider 4100 offers:

Active/Standby and Active/Active redundancy
fast switchover (sub-second to seconds)
synchronization accuracy between units < 5 ns
dual power supply

Ensures maximum uptime and service continuity.

Flexibility and scalability

Interfaces:

8× Ethernet (RJ45 / SFP)
optional 1GbE / 10GbE
E1/T1 (up to 20 ports internally)
1PPS, 10 MHz, ToD

Performance:

up to 2,000 PTP clients
up to 160,000 NTP transactions per second

Expansion:

up to 200 legacy ports (with TimeProvider XT)
