Pin Number
Pin Name
Pin Function
5, 6
RFCK, /RFCK
Reference Clock Differential Input. Input accepts any input, single-ended or differential:
TTL/CMOS, LVPECL, LVDS, HSTL, and SSTL. RFCK requires external termination.
See "Input Interface" section for details.
8, 9
XTAL2, XTAL1
Crystal Input. Directly connect a series resonant crystal across inputs. See “Quartz
Crystal Oscillator Specification” table. Place crystal as close to the input as possible,
keep XTAL and traces away from adjacent noisy traces to minimize noise coupling, and
place the XTAL on the same side as the SY89537L (component side).

100K LVPECL Output Drivers. Terminate all PECL outputs with 50 to VCCO-2V. Each
output pair has respective output frequency control (PSELx, PENx) pins. See "PECL
Output and Frequency Select Table" for proper coding. For low jitter applications, unused
PECL output pairs should be terminated with pull-down resistors. See "Output
Termination Recommendations" section for termination detail.

31, 32
LOUT0, /LOUT0
LOUT1, /LOUT1
LOUT2, /LOUT2
Differential LVDS Compatible Output Drivers. Output termination is 100 across the pair.
For low-jitter applications, unused LVDS output pairs should be terminated with 100
across the pair. See “Output Termination Recommendations” section for details.
