Table schema:
CREATE TABLE table_name_7 (socket VARCHAR, voltage VARCHAR, frequency VARCHAR, release_date VARCHAR)

Question: What is the socket related to the processor released on June 22, 2005, having a frequency of 1600MHz and voltage under 1.35V?
SQL: SELECT socket FROM table_name_7 WHERE frequency = "1600mhz" AND release_date = "june 22, 2005" AND voltage < 1.35
