Detailed introduction
The 499 allows the user to convert between two logic types; fast negative NIM (minus 800 mV) and TTL (plus 2 V). Plus, the polarity can be easily switched. 499 has a total of 16 conversion channels.
The upper part of the 499 provides 8 fast negative NIM channels for TTL logic conversion. The eight channels are divided into two sets of four-channel segments, which can be switched to standard or inverted outputs. The lower half of the module provides 8 TTL channels for fast negative NIM logic conversion, which are also divided into two sets of four-channel segments and can be switched to standard or inverting outputs.
The operating frequency from NIM to TTL is 60 MHz, while the operating frequency from TTL to NIM is 40 MHz. All outputs are DC coupled with no duty cycle limitations. The output impedance is 50 Ω, use a 50 Ω cable to connect to a 50 Ω load. The total latency for all channels is less than 10 ns.
