Product Details Supplier Info More products

Laser Components is offering a range of RF connectorised modules — including the DFF-DG-30 and DLL-RF-30 — from Photline Technologies.

The DFF-DG-30 is a D-type flip-flop module that is primarily intended for the retiming of high-data-rate signals.

It is also used to drive dual-drive LiNb03 modulators and, when associated with other logical circuits, it is used for applications including NRZ/RZ conversion, DPSK and DQPSK differential encoding and phase detection in PLL loops or memories.

The DLL-RF-30 is an adjustable-delay line connectorised module that is used for digital and analogue applications.
