260MHz, Crystal-to-LVCMOS/LVTTL
Frequency Synthesizer
ICS84021
General Description
The ICS84021 is a general purpose, Crystal-to-LVCMOS/LVTTL
High Frequency Synthesizer. The ICS84021 has a selectable
TEST_CLK or crystal input. The VCO operates at a frequency range
of 620MHz to 780MHz. The VCO frequency is programmed in steps
equal to the value of the input reference or crystal frequency. The
VCO and output frequency can be programmed using the serial or
parallel interface to the configuration logic.
Features
Two LVCMOS/LVTTL outputs
Selectable crystal oscillator interface or LVCMOS/LVTTL
TEST_CLK
Output frequency range: 103.3MHz to 260MHz
Crystal input frequency range: 14MHz to 40MHz
VCO range: 620MHz to 780MHz
Parallel or serial interface for programming counter and output
dividers
RMS period jitter: 14.7ps (typical), (N ÷ 4, V
DDO = 3.3V±5%)
RMS phase jitter at 155.52MHz, using a 38.88MHz crystal (12kHz
to 20MHz): 2.61ps (typical)
Offset
