The TLK3134 supports the IEEE 802.3 defined Management Data Input/Output (MDIO) Interface to allow
ease in configuration and status monitoring of the link. The bi-directional data pin (MDIO) must be
externally pulled up to 1.2 V or 2.5 V (VDDM) per the standard for MDIO.
The TLK3134 supports the IEEE 1149.1/1149.6 defined JTAG test port for ease in board manufacturing
test. It also supports a comprehensive series of built-in tests for self-test purposes including PRBS
generation and verification, CRPAT, CJPAT, Mixed/High/Low Frequency testing.
The TLK3134 operates with a 1.2 V core voltage supply, a 1.5/1.8 V HSTL I/O voltage supply and a 2.5 V
LVCMOS/bias supply.
The TLK3134 is packaged in a 19×19mm, 289-ball, 1mm ball pitch Plastic Ball Grid Array (PBGA)
package and is characterized for operation from –40°C to 85°C Ambient, 105°C Junction, and 5% power
supply variation at the balls of the device unless noted otherwise.
