5P49V6975 Datasheet | Renesas

Description The 5P49V6975 is a programmable clock generator intended for high-performance consumer, networking, industrial, puting, and data-munications applications. The device is a member of Renesas’ sixth generation of programmable clock technology, Versa Clock 6E. The 5P49V6975 contains an internal crystal, which eliminates the need for external crystal and load cap tuning. Two select pins allow up to four different configurations to be programmed and can be used for different operating modes (full function, partial function, partial power-down), regional standards (US, Japan, Europe) or system production margin testing. The 5P49V6975 can be configured to use one of two I2C addresses to allow the use of multiple devices in a system. Typical Applications - Ethernet switch/router - PCI Express 1.0/2.0/3.0/4.0 spread spectrum on - PCI Express 1.0/2.0/3.0/4.0/5.0 spread spectrum off - Broadcast video/audio timing - Multi-function printer - Processor and FPGA clocking - Any-frequency clock conversion - MSAN/DSLAM/PON - Fiber Channel, SAN - Tele line cards - Laser distance sensing Features - Integrated 25MHz crystal - Flexible 1.8V, 2.5V, 3.3V power rails - High-performance, low phase noise PLL, < 0.5ps RMS typical phase jitter on outputs - Four banks of internal OTP memory - In-system or factory programmable - Two select pins accessible with processor GPIOs or bootstrapping - I2C serial programming interface - 0x D0 or 0x D4 I2C address options allow multiple devices configured in a same system - Reference LVCMOS output clock - Four universal output pairs individually configurable: - Differential (LVPECL, LVDS, or HCSL) - Two single-ended (2 LVCMOS in-phase or 180 degrees out of phase) - I/O VDDs can be mixed and matched, supporting 1.8V (LVDS and LVCMOS), 2.5V, or 3.3V - Independent spread spectrum on each output pair - Output frequency ranges: - LVCMOS clock outputs: 1k Hz to 200MHz - LVDS, LVPECL, HCSL differential clock outputs: 1k Hz to 350MHz - Programmable output...
