OX-203

Holdover Reference Oscillator OX-203 OX-203 Description The Holdover Reference Oscillator family is designed specifically to meet the need for a high accuracy cost effective backup reference. These high stability oscillators will provide consistent, repeatable, extended holdover to the stated phase accuracy - making them ideal for applications where GPS, 1588 or other sources of timing are intermittent or prone to extended periods of unavailability. Features • Available in 8 hour and 24 hour version • Holdover accuracy available to ≤8μs and ≤1μs • Specifically designed for inter-operability with existing designs based on conventional OCXO’s. • Advanced digital compensation techniques take place inside the Holdover Reference - no need for programming or other user intervention. Applications • Precision Timing Applications in: • Wireless Base Stations • Wireless Backhaul • Digital Video Broadcast • Low latency optical networking • Power distribution • Test and Measurement Specifications Parameter Ouput Frequency Holdover Accuracy over 8 hours (ordering option) Holdover Accuracy over 8 hours (ordering option) Holdover Accuracy over 24 hours (ordering option) Warm up time Min 5 Typical Max 20 8.0 Units MHz μs Condition 150C range, Vs ±5%, Load +-5%, after 24 hours of operation 1.0 μs 150C range, Vs ±5%, Load +-5%, after 24 hours of operation 8.0 μs 150C range, Vs ±5%, Load +-5%, after 24 hours of operation 5 minutes to ±10ppb of final frequency (1 hour reading) @25 0C Vectron International • 267 Lowell Road, Hudson, NH 03051 • Tel: 1-88-VECTRON-1 • http://www.vectron.com Specifications (continued) Parameter Supply voltage Power Consumption Power Consumption Signal Load Signal Level (Vol) Signal Level (Voh) Duty Cycle Signal Load Output Power @ 5.0V Sub Harmonics Spurious Tuning Range Tuning Range Linearity Tuning Slope Control Voltage Range Phase Noise 1 Hz Phase Noise 10 Hz Phase Noise 100 Hz Phase Noise 1kHz Phase Noise 10kHz Maximum supply voltage Maximum output load Operable Temperature Range Storage Temperature Range Weight Dimensions -40 -55 0 1.65 -98 -125 -135 -143 -150 +-0.15 10% Positive 3.3 -90 -120 -130 -138 -145 6.0 50 85 85 Vdc dBc/Hz dBc/Hz dBc/Hz dBc/Hz dBc/Hz With Vs = 5.0 Vdc @10MHz 0 50 3 6 -25 -65 Fixed OCXO; No adjustment +-0.4 ppm 3.5 40 Sine Wave Ohm dBm dBc dBc 50 Ohm Load 50 Ohm Load 50 Ohm Load 60 15 0.5 HCMOS pF Vdc Vdc % With Vs=5.0 and 15pF load With Vs=5.0 and 15pF load @ (Voh-Vol)/2 Min 4.75 Typical 5 Max 5.25 3.1 1.5 Units Supply Vdc Watts Watts Condition during warmup steady state at 25 0C Output Maximum Ratings Vdc pF 0C 0C Mechanical 16.0 25.8x25.8x15.35 g mm Vectron International • 267 Lowell Road, Hudson, NH 03051 • Tel: 1-88-VECTRON-1 • http://www.vectron.com Typical Performance Data Holdover Perfomance - 96 Hours MTIE and TDEV - 0.3mHz loop filter bandwidth Vectron International • 267 Lowell Road, Hudson, NH 03051 • Tel: 1-88-VECTRON-1 • http://www.vectron.com Outline Drawing Pin Assignment Pin 1 2 4 6 7 13 15 17 19 Connection RF Output Do Not Connect Case Ground Do Not Connect EFC (Frequency Control) Do Not Connect Do Not Connect Do Not Connect Supply Voltage Ordering Information OX - 203 1 - D A E - 808 0 - 10M0000000 Product OX: OCXO Package Type 203: THT Version Height 1: 15.35mm Supply Voltage D: 5.0V Output A: HCMOS E: Sinewave Frequency Frequency Control 0: No Tuning 1: ±0.15 to ±0.4ppm Holdover Range 808: 8μs over 8 hours 824: 8μs over 24 hours Temperature Range 108: 1μs over 8 hours E: -40 to +85 0C J: -20 to +70 0C P: 0 to +50 0C *Note: not all combination of options are available.
