Description

The 9FGV1004C/9FGV1008C are members of Renesas’

PhiClock? programmable clock generator family. The 9FGV1004

provides 1 copy each of 2 integer-related frequencies, 2 copies of

a fractional or spread-spectrum frequency. The 9FGV1008

provided 1 integer frequency and 1 copy of a fractional or

spread-spectrum frequency. Four user-defined configurations may

be selected via two hardware select pins or two I2C bits, allowing

easy software selection of the desired configuration. Any one of

the four OTP configurations may be specified as the default when

operating in I2C mode. Four unique I2C addresses are available,

allowing easy I2C access to multiple components.

Features

? 1.8V, 2.5V or 3.3V power supplies

? Individual VDDO for each programmable output pair

? Supports HCSL, LVDS and LVCMOS I/O standards

? Low-Power HCSL technology for improved performance, lower

power and higher integration:

? Programmable output impedance of 85Ω or 100Ω

? Supports LVPECL and CML logic with easy AC coupling – see

AN-891 for alternate terminations

? On-board OTP supports up to 4 complete configurations

selectable via strapping pins or I2C

? Internal crystal load capacitors

? Programmable spread-spectrum modulation frequency and

amount

? < 150mW at 1.8V with LP-HCSL outputs at 100MHz

(9FGV1004)

? < 135mW at 1.8V with LP-HCSL outputs at 100MHz

(9FGV1008)

? 4 programmable I2

C addresses: D0, D2, D4, D6

? Easily configured with Renesas Timing Commander? software

or Web Configurator

? Space saving 4 × 4 mm 24-VFQFPN, 24-LGA (9FGV1004) and

3 × 3 mm 16-LGA (9FGV1008) packages

? Integrated crystal option (9FGV1004CQ, 9FGV1008CQ)
