GPS Module: The High-Precision Positioning Clock Cornerstone
In smart transportation, UAV surveying, and smart logistics, the GPS module serves as the core sensor for spatio-temporal information. Its performance hinges on an ultra-stable clock reference. Traditional 32.768 kHz crystals, with ±20 ppm stability and pronounced temperature drift, cannot meet the nanosecond-level synchronization demanded by satellite-signal demodulation.
A temperature-compensated crystal oscillator (TCXO) integrates on-chip compensation and voltage control to achieve ±0.5 ppm frequency stability across –40 °C to +85 °C, keeping total deviation within ±2 ppm. In automotive navigation, this enables millisecond cold-start via XIP technology and suppresses jitter with phase noise ≤ –150 dBc/Hz @ 10 kHz, delivering sub-meter accuracy even in urban canyons or tunnels.
13–55 MHz TCXO: Performance Engine for Dynamic Scenarios
With multi-constellation GNSS (GPS/BeiDou/GLONASS), 13–55 MHz TCXOs have become the standard clock for premium modules.
• High-frequency processing: A 26 MHz unit supports 480 Mbps data throughput, ensuring real-time carrier wipe-off and code alignment while cutting pseudorange error by >30 %.
• Environmental resilience: Digital temp-slope compensation keeps ±0.5 ppm stability from –40 °C to +105 °C, guaranteeing reliability for cars crossing thermal zones and drones at altitude. The band also supports L1/L5 dual-frequency demodulation for autonomous driving and IIoT.
Epson TG2016SKA: Redefining Miniaturized High-Precision Clocks
Epson’s TG2016SKA sets new benchmarks:
• Nanometer-level precision: ±0.5 ppm full-temp stability, aging ≤ ±0.5 ppm/year, phase noise –150 dBc/Hz @ 10 kHz for nanosecond GNSS sync.
• Ultra-low power & size: 1.7–3.63 V supply, 1.5 mA @ 26 MHz (40 % lower than legacy), 2.0 × 1.6 × 0.73 mm WSON saving 60 % PCB area—ideal for SiP and dense layouts.
• Smart compensation: Built-in VC-TCXO mode enables ±5 ppm dynamic trimming via pin control, eliminating MCU intervention and simplifying design.
At 26 MHz the device drives multi-channel RF front ends; post-reflow frequency shift ≤ ±2.0 ppm secures mass-production consistency.
MANDU, an Epson authorized partner, offers end-to-end support: precision matching for u-blox, ZK Micro and other GNSS chipsets; 48-hour sample delivery with –40 °C→125 °C cycling and 50 G vibration validation; mass-production guides and compensation-curve tuning that cut development cycles by >30 %.
Four core values for engineers
• Dual guarantee: ±0.5 ppm stability plus 10^9 h MTBF for lifetime zero-fault operation.
• Energy breakthrough: 1.5 mA standby extends battery life beyond five years and eases thermal design.
• Design compatibility: Pin-compatible with mainstream 3225 packages for drop-in replacement and rapid iteration.
• Local service: MANDU delivers 7×24 failure analysis and custom firmware, covering prototype to volume rollout.
As BeiDou-3 global coverage converges with 5G+BD applications, high-precision positioning becomes the backbone of an intelligent society. Epson TG2016SKA—nanometer accuracy, miniature footprint, all-scenario resilience—provides the irreplaceable clock cornerstone for next-gen GPS modules. Choose Epson, choose the benchmark of future positioning.
