Electrostatic Discharge (ESD)
The Tsi148 is a Charge Device Model test (CDM) Class II device as classified in the JEDEC
JESD22-C101-A Specification.
classifications for the Tsi148 device.
Table 34: Tsi148 ESD Classification
The Tsi148 has passed a CDM of 200V protection, but failed 500V protection. This rates the
Tsi148 as JEDEC Class II (200V to <500V). The exact threshold voltage has not yet been
determined but is between 200V and 500V. The most sensitive CDM Tsi148 pins are
PLL_VDD, PLL_VSS, PLL_OUTA, and CEO_TEST.
All other pins meet CDM Class III (500V to <1000V).
ESD Precautions
Precautions must be taken to reduce ESD exposure. The following practices are
recommended to help reduce ESD exposure:

Charge Device Model
Human Body Model
Machine Model
Wear wrist straps while seated
Wear footwear or heal straps while standing
Wear ESD smocks
Regularly check wrist straps and footwear
Ensure ESD dissipative flooring and work surfaces
Ensure work surfaces and equipment connected to electrical ground
Use ESD compliant chairs and carts, or “drag-chain” to the floor
Maintain humidity between 30% and 70% in all inspection and assembly areas
Minimize inspection and handling. If inspection is required, keep parts within trays (if
possible)
