NAME
DESCRIPTION
LVCMOS PARALLEL INTERFACE PINS
24
RCLK
LVCMOS_O Parallel Interface Clock Output Pin. Strobe edge set by RRFB configuration pin.
35-38,
41-44
R_OUT[7:0]
LVCMOS_O Receiver Parallel Interface Data Outputs – Group 1
19-22,
27-30
R_OUT[15:8]
LVCMOS_O Receiver Parallel Interface Data Outputs – Group 2
7-10,
13-16
R_OUT[23:16]
LVCMOS_O Receiver Parallel Interface Data Outputs – Group 3
CONTROL AND CONFIGURATION PINS
LOCK indicates the status of the receiver PLL
23
LOCK
LVCMOS_O LOCK = H; receiver PLL is locked
LOCK = L; receiver PLL is unlocked, R_OUT[23-0] and RCLK are at Tri-state.
Progressive Turn On Operation Selection
PTO = H; R_OUT[23:0] are grouped into three groups of eight, with each group switching about ±1
49
PTOSEL
LVCMOS_I UI to ±2 UI apart relative to RCLK. (Figure 17)
PTO = L; PTO Spread Mode, R_OUT[23:0] outputs are spread ±1 UI to ±2 UI and RCLK spread ±1
UI. (Figure 18) See Applications Informations section for more details.
Randomizer Control Input Pin (See Table 2 for more details.)
63
RAOFF
LVCMOS_I RAOFF = H, Backwards compatible mode for use with DS90C241 Serializer.
RAOFF = L; Additional randomization ON (Default), Selects 2E7 LSFR setting.
Receiver Data Enable
60
REN
LVCMOS_I
REN = H; R_OUT[23-0] and RCLK are Enabled (ON).
REN = L; R_OUT[23-0] and RCLK are Disabled (OFF), Receiver R_OUT[23-0] and RCLK Outputs are
in Tri-state, PLL still operational and locked to TCLK.
