The Tektronix DTG5334 data timing generator comes with three new output modules, expanding Tektronix's DTG5000 Logic Source family. The new DTG5334 provides a fast 3.35 Gbps data rate, while the output modules deliver increased performance and flexibility for serial data as well as parallel data applications. The DTG5334 is designed to help engineers satisfy compliance and functional test needs for many high-speed serial data standards such as SATA2, PCI Express and HDMI. Today's design engineers are faced with the challenge of performing functional, validation and compliance tests on circuits and system elements at increasing data rates. High-speed serial data standards require data timing generators with low output jitter and the ability to inject specified levels of intentional jitter as part of the testing process. Tektronix's DTG5334 and DTGM31 output modules are suitable for serial data generation at data rates up to 3.35Gbps with jitter modulation up to 250 MHz.

The DTG5334 data timing generator operates at data rates from 50 Kbps to 3.35 Gbps, with as many as eight output channels per mainframe and includes 64 M of pattern memory per channel. As many as 16 output channels can be supported though master/slave synchronization of two DTG5334 mainframes. The new DTGM21 output module enables tests on a wide range of native logic families by providing higher amplitude output (up to 5.35 V into 50 Ohm) and includes tri-state output control for bi-directional bus and memory device testing. The DTGM31 output module meets serial data validation and compliance stress testing needs with a jitter modulation input for frequencies up to 250 MHz and amplitudes up to 240 ps. External jitter control allows the emulation of real-world signals, enabling early testing and validation. The new DTGM32 provides two jitter modulation inputs specifically to meet the needs of standards such as HDMI with jitter frequencies up to 50 MHz and amplitudes up to 2 ns.
