CLOCK DISTRIBUTION CIRCUIT Description
The IDT6P30006A is a low-power, eight output clock distribution circuit. The device takes a TCXO or LVCMOS input and generates eight high-quality outputs. It includes a redundant input with automatic glitch-free switching when the primary reference is removed. The primary input may be selected by the user by pulling the SEL pin low or high. If the primary input is removed and brought back, it will not be re-selected until 1024 cycles have passed. The IDT6P30006A specifically addresses the needs of handheld applications in both performance and package size. The device is packaged in a small 4mm x 4mm 24-pin QFN, allowing optimal use for limited board space.
IDT6P30006A Features
Packaged in 24-pin QFN LVCMOS or TCXO sine wave input +1.8 V operating voltage Glitch-free input switching Eight buffered square wave outputs at 1.8 V LVCMOS levels
Individual output enables controlled via I2C or OEx Pb free, RoHS compliant package Industrial temperature range (-40°C to +85°C)
