MICROREF-ZL

Product catalog summary

Overview
The MICROREF-ZL is a compact Time & Frequency reference generator designed for OEM customers requiring high integration at a low cost. It is supplied without a rack to allow integration into existing equipment needing synchronization. The board's dimensions (127 x 55 mm) make it compatible with Eurocard slots and 19”/1U racks. It features interfaces such as RS232 with customizable commands, 10/100 Ethernet with SNMPv2 protocol, and supports web-browser or custom GUI integration.

Features
- High stability 10 MHz sine wave output, tunable from -2dBm to 16 dBm.
- 1PPS TTL output with 50 ohms impedance.
- Internal OCXO with +/- 1E-10 aging per day in holdover condition.
- 12-channel GPS receiver with automatic tracking and timing error management.
- Four independent TTL signal outputs for board status indication.
- RS232 serial connection and Ethernet 10/100 interface with TCP/IP protocol.
- Power supply range from 8 VDC to 30 VDC.
- Compact mechanical format (55 x 127 x 30 mm).
- Management software compatible with Windows OS.
