Time & Frequency Distribution
TFD-100 series
Modular Time & Frequency Distribution/Generating Unit
The TFD-100 series is a 1U, rack 19″ mount, modular time and frequency distribution unit. It provides the precise distribution of any frequency from 1PPS up to 10MHz include most popular standards: 1PPS (TTL), IRIG-DCLS (TTL), 10MHz (TTL and Sine).
You can order the following base modules that differ in power supply:
- TFD-101 – single 85-265VAC/100-370VDC power supply
- TFD-102 – dual, redundant 85-265VAC/100-370VDC power supplies
- TFD-110 – single 48VDC (36-75VDC) power supply
- TFD-120 – dual, redundant 48VDC (36-75VDC) power supplies
- TFD-111 – dual, redundant 85-265VAC/100-370VDC and 48VDC (36-75VDC) power supplies
Available distributor modules:
- TFM-1218 – high precision 1/8 digital distribution module (TTL @50Ω) for 1PPS, IRIG-DCLS, 10MHz. 1x input, 8x output. Sockets: BNC (TFM-1218BNC) or SMA (TFM1218SMA). See flyer
- TFM-1228 – 1/8 analog 10MHz sinus (8dBm @ 50Ω) distribution module. 1x input, 8x output. Sockets: BNC (TFM-1228BNC) or SMA (TFM1228SMA)
Key features:
- 1PPS signal (TTL) distribution
- 10MHz (TTL/Sine) distribution
- IRIG-DCLS (TTL) distribution
- BNC or SMA sockets
- Redundant power supply 230VAC or/and 48VDC
