64-Pin EPAD-TQFP (H64-1)
PIN DESCRIPTION
Pin Number
Pin Name
Type
Pin Function
5, 6
HSTL_CLK,
HSTL
Differential clock input selected by CLK_SEL. Can be left floating if not selected. Floating
/HSTL_CLK
Input
input, if selected, produces an indeterminate output. HSTL input signal requires external
termination 50
to GND.
8, 9
LVPECL_CLK,
LVPECL
Differential clock input selected by CLK_SEL. Can be left floating. Floating input, if
/LVPECL_CLK
Input
selected, produces a LOW at the output. Requires external termination. 75k
pull-up.
7
CLK_SEL
LVTTL
Selects HSTL_CLK input when LOW and LVPECL_CLK output when HIGH. 11k
Input
pull-up. Default condition selects LVPECL_CLK if left open.
11
OE
LVTTL
Enable input synchronized internally to prevent glitching of the Q0-Q21 and /Q0–/Q21
Input
outputs. Must be a minimum of three clock periods wide if synchronous with the CLK
inputs and must meet the t
S and tH requirements (refer to “AC Electrical Characteristics”
section). If asynchronous, must be a minimum of four clock periods wide. 11k
pull-up.
63, 61, 59, 57, 55, 53
Q0–Q21
HSTL
Differential clock outputs from HSTL_CLK when CLK_SEL = LOW and LVPECL outputs
51, 47, 45, 43, 41, 39
Output
when CLK_SEL = HIGH. HSTL outputs must be terminated with 50
to GND. Q0–Q21
37, 35, 31, 29, 27
outputs are static LOW when OE = LOW. Unused output pairs may be left floating.
25, 23, 21, 19, 15
62, 60, 58, 56, 54, 52
/Q0–/Q21
HSTL
Differential clock outputs from HSTL_CLK when CLK_SEL = LOW and LVPECL outputs
50, 46, 44, 42, 40, 38
Output
when CLK_SEL = HIGH. HSTL outputs must be terminated with 50
to GND. /Q0–/Q21
36, 34, 30, 28, 26
outputs are static HIGH when OE = LOW. Unused output pairs may be left floating.

VCCI
VCC Core
Core V
CC connected to 3.3V supply. Bypass with 0.1F in parallel with Power 0.01F
low ESR capacitors as close to V
CCI pins as possible.

VCCO
VCC Output
Output Buffer V
CC connected to 1.8V supply. Bypass with 0.1F in parallel with 0.01F
33, 48, 49, 64
Power
low ESR capacitors as close to V
CCO pin as possible. All VCCO pins should be
connected together on the PCB.
10
GND,
Ground pin and exposed pad must be connected to the same ground plane.
Exposed Pad
2, 3, 12, 13
