    • Provided is a test socket capable of being used more flexibly for solid-state image pickup devices of different shapes and of performing locating of the solid-state image pickup devices more precisely. The test socket houses a device under test (DUT) which is a solid-state image pickup device while a test is being performed. The test socket comprises: first locating means for locating the DUT in an X direction parallel to a ceiling plane of the DUT in a housed state; urging means for urging the first locating means in a Z direction perpendicular to the ceiling plane of the DUT in the housed state; and position setting means for setting an upper limit of movement in the Z direction of the first locating means caused by the urging means to set a position in the Z direction of the first locating means relative to the DUT.

    • A semiconductor integrated circuit that self-tests the skew margin of the clock and data signals in an LVDS. A clock signal CKB1 is held in flip-flop circuit 105 synchronously with checking clock signal A1. Checking pattern signal PAT_A is held in flip-flop circuit 104 synchronously with checking clock signal A2. When the skew margin of clock signal CKA_IN and data signal DA_IN are checked, the checking signal TCKA of flip-flop circuit 105 is input instead of clock signal CKA_IN, and the checking signal TDA of flip-flop circuit 104 is input instead of clock signal DA_IN. The timing relationship between clock signal CKB7 and checking timing signal A1 and the timing relationship between clock signal CKB7 and checking timing signal A2 are controlled independently by timing control circuit 109.
    • 一种半导体集成电路,可以自我测试LVDS中时钟和数据信号的偏移余量。 时钟信号CKB1与检查时钟信号A1同步地保持在触发器电路105中。 检查模式信号PAT_A与检查时钟信号A2同步地保持在触发器电路104中。 当检查时钟信号CKA_IN和数据信号DA_IN的偏斜边缘时,输入触发器电路105的检查信号TCKA而不是时钟信号CKA_IN,并且输入触发器电路104的检查信号TDA而不是时钟信号 DA_IN。 定时控制电路109独立地控制时钟信号CKB7与检查定时信号A1之间的时序关系以及时钟信号CKB7与检查定时信号A2之间的定时关系。
