DC Characteristics
Note (1): Measured at TP3 as defined in the IEEE 802.3ak-2004 specifications. This value is needed in each IPG to maintain the SIG_DET function active. The
BBT3821 will provide a BER < 1 in 10-12 under the conditions of clause 54.6.4.1 of the specification.
Note (2): Measured at TP2 as defined in the IEEE 802.3ak-2004 specifications.
Note (3): CX4 Mode not specified for low power Vdd = 1.35V operation; “Standard Device” conditions are required.
Note (1): BBT3821LP-JH only.
Note (1): Measured using CJPAT.
Note (1): XENPAK MSA recommended for LASI pin.
Note (2): For MDIO and LASI pins.
Note (3): Only for RSTN and MDC pins.
