CDCEL937-Q1

The CDCEL937-Q1 is modular PLL-based low-cost high-performance programmable clock synthesizers, multipliers, and dividers. It generates up to seven output clocks from a single input frequency. Each output can be programmed in-system for any clock frequency up to 230 MHz, using up to three independent configurable PLLs.The CDCx937 has separate output supply pins, VDDOUT, which is 1.8 V for CDCEL937 and to 2.5 V to 3.3 V for CDCE937.

Features of the CDCEL937-Q1 are:(1)Qualified for Automotive Applications; (2)Member of Programmable Clock Generator Family CDCE913/CDCEL913: 1-PLL, 3 Outputs CDCE925/CDCEL925: 2-PLL, 5 Outputs CDCE937/CDCEL937: 3-PLL, 7 Outputs CDCE949/CDCEL949: 4-PLL, 9 Outputs; (3)In-System Programmability and EEPROM Serial Programmable Volatile Register Nonvolatile EEPROM to Store Customer Setting; (4)Flexible Input Clocking Concept External Crystal: 8 MHz to 32 MHz On-Chip VCXO: Pull Range ±150 ppm Single-Ended LVCMOS up to 160 MHz; (5)Selectable Output Frequency up to 230 MHz; (6)Low-Noise PLL Core Integrated PLL Loop Filter Components Low Period Jitter (Typ 60 ps); (7)Separate Output Supply Pins CDCE937: 3.3 V and 2.5 V CDCEL937: 1.8 V.

The absolute maximum ratings of the CDCEL937-Q1 can be summarized as:(1)Supply voltage range :0.5 to 2.5 V; (2)Input voltage range(2) (3):0.5 to VDD + 0.5 V; (3)Output voltage range(2):0.5 to Vddout + 0.5 V; (4)Input current (VI < 0, VI > VDD): 20 mA; (5)Continuous output current :50 mA; (6)Storage temperature range :65 to 150 °C.
