Programmable Clock Generator 5P49V5923 DATASHEET Description Features The 5P49V5923 is a programmable clock generator intended Generates up to two independent output frequencies for high performance consumer, networking, industrial, High performance, low phase noise PLL, <0.7 ps RMS computing, and data-communications applications. typical phase jitter on outputs Configurations may be stored in on-chip One-Time 2 Two fractional output dividers (FODs) Programmable (OTP) memory or changed using I C interface. This is IDTs fifth generation of programmable clock Independent Spread Spectrum capability on each output technology (VersaClock 5). Four banks of internal non-volatile in-system programmable or factory programmable OTP memory The frequencies are generated from a single reference clock. 2 The reference clock can come from one of the two redundant I C serial programming interface clock inputs. A glitchless manual switchover function allows Three LVCMOS outputs, including one reference output one of the redundant clocks to be selected during normal I/O Standards: operation. Single-ended I/Os: 1.8V to 3.3V LVCMOS Two select pins allow up to 4 different configurations to be programmed and accessible using processor GPIOs or Input frequency ranges: bootstrapping. The different selections may be used for LVCMOS Reference Clock Input (XIN/REF) 1MHz to different operating modes (full function, partial function, partial 200MHz power-down), regional standards (US, Japan, Europe) or LVDS, LVPECL, HCSL Differential Clock Input (CLKIN, system production margin testing. CLKINB) 1MHz to 200MHz 2 The device may be configured to use one of two I C Crystal frequency range: 8MHz to 40MHz addresses to allow multiple devices to be used in a system.
