Time and Frequency Distribution TDC3303 Time Code Distribution Chassis "Smarter Timing Solutions" 2x10 Autoswitch Distribution Amplifier FEATURES The TDC3303 is a dual-input, ten-output, low-frequency distribution amplifier in a 1U rackmount chassis. The TDC3303 provides ten isolated copies of an input signal and is ideal for distributing IRIG-A, B, E, G or H time code. Fault sensing . 10-channel, low-frequency of signal levels is provided on all inputs and outputs, status is easily visible via front-panel LED indicators, and monitoring via an RS-232 port is a standard feature. In addition, remote control and status monitoring via a network port is available as an option. The TDC3303 is unique in the industry - no other low-cost system offers this combination of capabilities and performance. . Ideal for IRIG-A, B, E, G or H Autoswitching The TDC3303 can be configured for single or dual input operation. If two inputs are available then the TDC3303 will monitor the input signals. If an input is removed or the amplitude is greatly reduced it will automatically switch to the other input. This feature ensures that your critical signals are always present. Alarm Input The TDC3303 is compatible with the alarm output signal from the Meridian II and Tycho II Precision TimeBase time and frequency standards. If one of these units is sourcing the TDC3303 and its alarm output goes active, then the TDC3303 will automatically switch to the backup source. Since this alarm input may be cascaded to multiple TDC3303 units, bank switching is supported by simply connecting the inputs with coaxial cable and BNC T-adapters. Status Indicators Front panel LEDs provide you at-a-glance status of the distribution chassis. The TDC3303 provides LED indicators for the power supply(ies), the two inputs, all output signals and a summary alarm indicator. The summary alarm is also available as an open-collector output on a rear-panel BNC. Control and Status Monitoring The TDC3303 can be configured and monitored by means of an RS-232 serial port. Both the switch and output status can be monitored in this way. For remote control and monitoring, a network port is available as an optional upgrade. Dual Power Supplies For the highest level of power source and supply fault-tolerance, the TDC3303 Time Code Distribution Chassis supports dual redundant, AC or DC power supplies. The two power supplies can be any combination of AC/AC, AC/DC, or DC/DC. High Reliability The TDC3303 uses EndRun’s power-efficient, fanless design and thermal packaging that achieves an estimated MTBF of over 20 years. The system is made in America, backed by a two-year warranty, a 60-day money-back guarantee, and supported by EndRun’s top notch technical support team free of charge! sine wave distribution (100 Hz to 100 kHz). time code distribution. .
