The GX5296’s timing generator supports 8 timing phases and 4 windows (drive and sense timing). Each phase and window are comprised of two-timing edges - assert/de-assert and a sense data strobe. Sub-nanosecond timing resolution is supported for each of these edges. The 8 phases and 4 windows are available for mapping edge timing to a specific channel. Up to 64 unique time set values can be defined for each phase / window and are selectable on per sequence step basis. Additionally, six data formats are supported - NR (no return), R0, R1, RHiZ, RC (Return to Complement), and RSC (Return Surround with Complement).
Pin electronic resources are independent on a per channel basis and include a full-featured PMU for DC characterization of DUTs. The PMU can operate in the force voltage/measure current or force current/measure voltage mode. Additionally, 4 additional pin electronics resources are available for use as timing and/or control resources – providing programmable drive and sense levels from -2 to +7 volts.
The GX5296 employs a PLL based, clock system which offers programmable vector clock rates up to 125 MHz. In addition, a Clocks per Vector (CPV) divider is available, providing additional clocking and edge placement flexibility. External input and output synchronization signals are also supported, providing the ability to synchronize the GX5296 to external events.
The GX5296’s offers a full-featured sequencer. Capabilities include conditional jump, unconditional jump, subroutine jump, and looping. Additionally, the sequencer has the ability to handshake with various signals in order to synchronize with a UUT. Handshaking settings can be selected on a per Step basis using various Handshake Pause and Resume resources. Total sequencer memory size is 4096 steps.
