DESCRIPTION

· The CDCE937 and CDCEL937 are modular PLL-based, low-cost, high-performance, programmable clock synthesizers, multipliers, and dividers.
· They generate up to 7 output clocks from a single input frequency, with each output programmable up to 230MHz using up to three independent PLLs.
· The devices feature separate output supply pins (1.8V for CDCEL937 and 2.5V to 3.3V for CDCE937) and accept external crystal or LVCMOS clock inputs.
· An on-chip VCXO allows synchronization of the output frequency to an external control signal.

FEATURES

· Member of the Programmable Clock Generator family with multiple PLL and output configurations.
· In-system programmability with EEPROM for storing customer settings.
· Flexible input clocking with external crystal (8MHz to 32MHz) or LVCMOS clock (up to 160MHz).
· Low-noise PLL core with integrated loop filter components and low period jitter (typical 60ps).
· Programmable SSC modulation for EMI reduction and 0PPM clock generation.
· Wide temperature range (-40°C to 85°C) and available in TSSOP package.

APPLICATIONS

· High-Definition Television (HDTV).
· Set-Top Box (STB) and IP-STBs.
· DVD players and recorders.
· Printers and other consumer electronics.
