Description
DIN
Data Input. LVTTL levels inputs. Data on these pins are loaded
into a 10-bit input register.
TCLKR/F
I
Transmit Clock Rising/Falling strobe select. LVTTL level input.
Selects TCLK active edge for strobing of DIN data. High selects
rising edge. Low selects falling edge.
+ Serial Data Output. Non-inverting Bus LVDS differential output.
Serial Data Output. Inverting Bus LVDS differential output.
Serial Data Output Enable. LVTTL level input. A low puts the Bus
LVDS outputs in TRI-STATE.
Powerdown. LVTTL level input. PWRDN driven low shuts down
the PLL and TRI-STATEs outputs putting the device into a low
power sleep mode.
Transmit Clock. LVTTL level input. Input for 20 MHz–66 MHz
system clock.
Assertion of SYNC (high) for at least 1024 synchronization
symbols to be transmitted on the Bus LVDS serial output.
Synchronization symbols continue to be sent if SYNC continues to
be asserted. TTL level input. The two SYNC pins are ORed.
Digital Circuit power supply.
Digital Circuit ground.
