Programmable Clock Generator 5P49V5925 Description The 5P49V5925 is a programmable clock generator intended for high performance consumer, networking, industrial, computing, and data-communications applications. Configurations may be stored in on-chip One-Time Programmable (OTP) memory or changed using I2C interface. This is IDT’s fifth generation of programmable clock technology (VersaClock® 5). The frequencies are generated from a single reference clock. The reference clock can come from one of the two redundant clock inputs. A glitchless manual switchover function allows one of the redundant clocks to be selected during normal operation. Two select pins allow up to 4 different configurations to be programmed and accessible using processor GPIOs or bootstrapping. The different selections may be used for different operating modes (full function, partial function, partial power-down), regional standards (US, Japan, Europe) or system production margin testing. The device may be configured to use one of two I2C addresses to allow multiple devices to be used in a system. Pin Assignment Features • Generates up to four independent output frequencies • High performance, low phase noise PLL, <0.7 ps RMS typical phase jitter on outputs • Four fractional output dividers (FODs) • Independent Spread Spectrum capability on each output • Four banks of internal non-volatile in-system programmable or factory programmable OTP memory • I2C serial programming interface • Five LVCMOS outputs, including one reference output • I/O Standards: – Single-ended I/Os: 1.8V to 3.3V LVCMOS • Input frequency ranges: – LVCMOS Reference Clock Input (XIN/REF) – 1MHz to 200MHz – LVDS, LVPECL, HCSL Differential Clock Input (CLKIN, CLKINB) – 1MHz to 200MHz – Crystal frequency range: 8MHz to 40MHz • Output frequency ranges: – LVCMOS Clock Outputs – 1MHz to 200MHz • Individually selectable output voltage (1.8V, 2.5V, 3.3V) for each output • Redundant clock inputs with manual switchover • Programmable loop bandwidth • Programmable slew rate control • Programmable crystal load capacitance • Individual output enable/disable • Power-down mode • 1.8V, 2.5V or 3.3V core VDDD, VDDA • Available in 24-pin VFQFPN 4mm x 4mm package • -40° to +85°C industrial temperature operation 1 7 24-pin VFQFPN 19 13 XOUT XIN/REF VDDO3 CLKIN NC OUT2 CLKINB CLKSEL OUT3 NC VDDO2 VDDA EPAD GND 2 3 4 5 6 8 9 10 11 12 14 15 16 17 18 20 21 22 23 24 |
