  Part Number: LMK00301 Hi, Does Bank A and Bank B have any phase delay if we configure both bank a and bank b with same output signal type (such as LVDS)? What is the phase delay spec between Bank A and Bank B? Thanks!

  Part Number: LMK00301 Hello, I have a design that has a modular expansion system where each expansion slot has a 25MHz clock running LVDS out of the LMK00301. Because of the nature of the design, each of these slots may or may not have a card loaded…

  Part Number: LMK00301 The LMK00301 Datasheet Sec 7.5 (Electrical Characteristics) states that the Differential Input Common Mode Voltage (Vcmd) is 0.25V MIN. If AC coupling is used, like you say it can be, is an external bias network required to create…

  Part Number: LMK00301 The data sheet for the LMK00301 page 26 regarding AC coupling appears to be completely wrong and in need of a re-write. Contrary to what the whole page is about, the LVDS driver output DOES NOT NEED A DC CURRENT RETURN PATH. No LVDS…

  Part Number: LMK00301 Hi Team, As far as i can see in order to configure the different outputs banks of the buffer you have to send either '1' or '0' the the designated pins. Since this device is the clock source for my FPGA when startup i want…
