BCM4414xH0E5035yzz
Signal Characteristics
Specifications apply over all line and load conditions, unless otherwise noted; boldface specifications apply over the temperature range of
–40°C ≤ TCASE ≤ 100°C (T-Grade); all other specifications are at TCASE = 25ºC unless otherwise noted. Please note: For chassis mount model, Vicor part
number 42550 will be needed for applications requiring the use of the signal pins. Signal cable 42550 is rated up to five insertions and extractions.
To avoid unnecessary stress on the connector, the cable should be appropriately strain relieved.
Serial Clock input (SCL) AND Serial Data (SDA) Pins
• High-power SMBus specification and SMBus physical layer compatible. Note that optional SMBALERT# is not supported.
• PMBusTM command compatible.
